Hi Simon, not much to it is there :) I'm assuming you listen to a lot of file based audio? :scratch:
What are the funky room treatment tiles you have there? I like the look of those even if they do look a tad odd, I could get used to it ;)

Yeh, most of my cd's are on the mac as ALAC, there's a couple of hundred records just out of shot and I've just sold the SME10/V and am awaiting on vendors opening up after New Year to replace it. Should be sorted this weekend.
The tiles are just some boggo acoustic foam ones from t'Bay. They run ceiling to floor in each corner of the room and between the speakers. The slightly less noticeable thing is the £700 worth of theatre curtain. Heavy crushed velvet, double lined with canvas, they utterly kill the splash from the UPVC windows when I can be arsed to close them.
I set the room up while borrowing one a Trinnov room correction unit from Keith at Purite. The room measures flatter than a witches tit as it is currently set-up until you get below 50hz where the floorboards are quite active. I might have the spectrums lying round somewhere, it was better than 1db from 50hz to 20khz.

Hmmm, ebay indeed :) I think I'll take a look about :eyebrows:
I could do with similar curtains myself, might appear to be expensive, but no doubt worth it. I'm sure you shut them earlier at this time of year, I know I would with no net curtains ;)
Hope you get your 509s back shortly & your vinyl front end sorted :cool:

Have you tried any absorption tiles directly behind the listening chair? (Assuming there is a sensibly placed wall there).
I found that to have excellent affect in my system, focussing the sound quite noticeably.
After the acquisition of my omni MBL speakers they were the only room treatment I kept, in fact - panels placed behind the speakers, which had worked well previously, had a bad affect on the sound.
Nice looking system
I was without a TT for over a year so understand the frustration.
I am sure in time you find the right TT for yourself

For me it killed the slap echo and helps ameliorate the bass nodes in the corners, it doesn't do a huge amount for the bass but enough to be worthwhile.

Hi Andrew, its very cheap on ebay the more you buy the cheaper it is. The long stand up one's in the pic I made myself by sticking the foam to carboard carpet tubes. In one word on improvements "everything". Best to buy a couple at a time then just keep adding, there really is no going back after using these panels, just don't go too far or you will kill the sound. I would say buy some I don't think you'll regret it:)

Yep, buy a few bits at a time.
One of the best hifi upgrades I have heard was when someone removed the absorptive panels he had surrounded his room with! It's easy to get too carried away and not realise the damage you are doing to the sound.
Obviously varies from rom to room, but a possible way to try is to damp the area behind you and keep the speaker area slightly more "lively," as in a concert hall, where one os surrounded by others in the audience. You don't need to overdo it, but I remember hearing a heavily treated (by a qualified acoustician) room thus done, and the speakers played in it sounded amazing, even the little cheapies he had just sounded "smaller" than the bigger models, rather than significantly inferior.. Sorry if it's granny sucking eggs here, as many of you will have far more practical experience than I.

It is very easy to go over the top with room treatments and it is one of the few things that i would only do with a room measurement set-up on hand. When I originally put mine up there was a lot of back and forth over a couple of weeks, while I had one of Keith's Trinnovs to hand to measure the room. I ended up removing and replacing quite a few areas of treatment that helped the room to measure flat, but killed the reverberation, no one wants a completely dead room after all because music isn't mixed in completely dead rooms.
Branko was very... accommodating ;-)
I agree you can go over the top and kill the sound. I did a few main areas of the room listened for a week or so then added again and so on till I was happy with it. I have spent alot of cash on hi fi over the past 20yrs and in my opinion the £130 I spent on these panels was by far the biggest upgrade I have ever heard.. Every room is going to be differant ie furniture carpets wood floors, but I think whatever your room is there would be benifits from these panels just dont over do it....
Jason
Branko was very... accommodating ;-)
I'm even more amazed now! We're not worthy.....
For taming a lively room without making everything sound dead and overly damped, try diffusors in place of absorbers. Particularly good on the wall behind the listening area if that is reasonably close.
For Mac users, this is a superb measurement software suite:
http://supermegaultragroovy.com/products/FuzzMeasure/
Just add a sound card and a reasonably flat mic.
I use it with great results.

Nah it's not here yet. It would have been if I'd chosen one from Branko's demo stock, but this one is coming straight from Kuzma. It's a special order in Black, to best match my cartridge, should be a good match with the touch of brass on the balance weights offsetting the cartridge parts. (Yeh, I'm that anal).

Rest assured I will provide pictures as soon as it is in situ. Should be a busy week, the EAR 509's will be back from TDP early in the week as well.
Thinking about a change of TT myself so awaiting your remarks. I worked out a long time ago that you are hyper critical so I know that if you rate the Kuzma it might be worth having......
For me it killed the slap echo and helps ameliorate the bass nodes in the corners, it doesn't do a huge amount for the bass but enough to be worthwhile.
My TubeTraps do exactly the same thing: reduce flutter echo in the room quite dramatically. Improves intelligibility and clarity.

Darren, I used to have the 9" version but replaced it with the SME 10/V combo- it wasn't really an upgrade over the Kuzma. The SME had better speed stability over the stock AC motor it didn't sound any better other than in that area. I already have a new DC controller built up for the incoming Kuzma, i need to make a top plate for the motor housing before I order the new motor though.

There's a bit of a big bugger lurking under there. The amp is 200 watt into 8ohm and doubles down into 4ohm.

The caps are a fair old size as well, Coke can size and there's four of them. 80,000uf per channel.

The inputs are all relay controlled from the front panel, there's a satisfying silicon click as they flip over.

With 500VA of transformer per side, 160,000uf of capacitance on tap and 8 output devices per channel it does need a little help keeping cool.

And there we have it the Muse Model 200, stereo power amp. This one has the remote control attenuation built in, so it's basically a power amp with adjustable gain (or resistor ladder attenuation depending on where you are between -65 db and + 30).
How about a pic of the front panel..........?

But actually, it doesn't really, does it - the output stage is relatively lightly loaded and the heat sinks are more than adequate :).
I've seen this particular amp a number of times and it is actually rather a handsome, if bluff, thing - austere, but visually well balanced - purposeful without trying too hard.

Martin, the amp looks big dick, but once you get inside it there's no magic. The output stage is simple, the PSU chunky and the pre-amp section positively prosaic, hell the volume control is on-chip, not exactly an accepted recipe for success.

Mmmm, they are quite different sounding speakers the Yams are basically a great big pair of headphones, they are very explicit and shine a light on the mids. The Focals go deeper than the Yams and the treble is slightly better judged as the tweeter on the Focals covers a greater range and there's far less crossover in the Focals.
It's a tough call they both do things remarkably well. At the end of the day i think it might just come down to keeping the Yams because they represent a new sound.
I'll have to figure out how much the Focals owe me and see if anyone is interested. Tehy'll going for less than half the list price that's for sure, somewhere around £1500, but it is totally the wrong time of year to sell speakers- totally.
Yonks ago, to get the most "realistic" balance on the NS1000's, you set the mid control to 10 o'clock and the tweeter one to eleven o'clock.
Just be VERY grateful that you don't have NS10's. These godawful little screechers have set the trend for so many desktop "monitors" and even AVI climbed on the bandwagon with some of their passive speakers (and probably most of the active ones, in tamed form as well - cough - )

21-07-2012, 10:59

Yep, so many sound engineers used those 'orrible NS10.
I think that's why sound engineers have a (often well deserved!) reputation for being as deaf as a deaf thing. :eyebrows:
An amateur muso told me that NS10's can be good for mixing, as mixes done with them play back well on better systems. I remember them letting it all hang out and SOS magazine has done at least two articles on them, with properly conducted objective backup explaining why. One of these articles also compared a few dozen of the competition as well and it's interesting that even ATC bump up the upper mid on their later (and very early) speakers, to give a brighter and more "deeeeetailed" balance (so do AVI, but we won't go there :))

Well the 135's certainly sounded loud enough to my ears with no hint of clipping, and Mark loves to play em loud, far louder than I ever will. He normally runs ES14's backed up by his Rel Stadium sub. The Yammies weren't left wanting for max SPL when played, even without the sub.

I'm not really in much of a position to say a great deal about them until I resolve the -3db issue on the right hand channel of my amp and I'm a week away from having enough time to take that to bits to investigate the pre-amp section with a scope and my signal generator.
I can tell you what they sounded like at Mark's. They were dynamic, visceral, the bass was tight but not hugely extended. The treble and mid integration is excellent though the mid is better than the treble, the treble seems maybe a touch lacking in ultimate extension, though I imagine in 5 years time I'd not notice that roll-off, as it stands I can still hear 17k, just.
They really do have the detail across the midrange and the resolving power of a decent pair of electrostatics, though as noted this doesn't extend to 20k. The dispersion on them is simply stunning, they image no matter where you sit, quite a feat. I didn't find them to be hard, or metallic or any of the other obvious visually cued claims that have been made for them over the years. The bass could perhaps do with being a little better integrated where it hands over to the mid but that's really nit-picking on a large speaker with 3 drivers that sounds amazingly well integrated otherwise.
They are definitely deserving of monitor status and no doubt were way ahead of their time when introduced to the market. I'm pretty sure that they are a keeper, I'll know for sure once my amp is fixed up. Toppsy has done a first rate job on the cabinets, though my preference would be for a 'grain filled' finish on the veneer rather than the oiled finish that they have. Given that there's currently pairs on ebay asking up to £1500 with nowhere near the quality of finish that these have they represent a real bargain.
Well, I think that is an excellent description Si and entirely agrees with my own thoughts.
With regards to the treble, I would add that whilst it doesn't sound hard, metallic, spitty etc., it also doesn't sound particularly finely shaded. In contrast, the mid has remarkable resolution - if you can't hear something in the mid with these speakers it doesn't exist and makes my ES14's sound slightly veiled - very few speakers can achieve this. On the other hand the mid is quite 'cool' in nature and although the bass driver is quick, it does have a slightly different character where it passes over to the mid. I would also say that whilst the Yamaha's sound dynamic (remarkably so sometimes), the actual micro dynamic in the mid is not as pronounced as it could be. Contrary to some opinion, I found my 135's drove them with ease and they were noticeably more efficient than my ES14's. As Simon writes, the bass was quite remarkably visceral and certainly the mid and upper bass had excellent texture and focus.
Please keep to the topic now, chaps.

It's been a while since i did anything on the Su-Prefix (SIC) and I've been meaning to shift the cartridge loading resistors to a back panel DIN so I can swap them over at my leisure as required by potential cartridge swaps.

I'm using Charcroft resistors, maybe they sound better because i know they cost a fortune each- maybe they do genuinely improve things- frankly I don't care, they are the ones I use.

http://farm9.staticflickr.com/8020/7683601622_ace30360ea_c.jpg
I wired them in with 0.5mm silver because that's what I had to hand. They are just wired straight from the pcb pads to the DIN socket.

Sorry to butt in folks, but I seem to remember they (the pins) are, since they oxidise*** in humid environments...

Andre, they are silver over nickel plated and the pins are cuTe copper according to the nice man from Canford on the telephone not two weeks ago when I made just this very enquiry.
Canford- PREH DIN sockets.
And for the record silver doesn't oxidise, the tarnish you get on silver is from sulphur in the form of hydrogen-sulphide in the air.

Mike, it's nice that you think that I might have the knowledge and ability to achieve that, I'm not so sure. I know that I certainly don't have the time required to scratch build large projects.
There's a world of difference between simulating the crossover in a pair of speakers and then replacing old components with newer ones with nominal values that won't upset the apple cart and designing the crossover from scratch based on the measurements of the drivers and the box dimensions.
Modifying gear allows me to just dip in and out of the process without having to give over large swathes of my time to projects. That's enough to satisfy my desire to 'make' things.

The vintage amp i use now, i fully rebuilt which took me only 4 months even though there was a ten fold component count, compared to the scratch built amp, i got it done in less than a quarter of the time with the same work commitments over my head...However i still need to sort out the new hardware on the back pannel but other things take preference such as a turntable plinth that i'm 2/3 way through finishing at the mo :)

Thanks for your reply, I only wish I had the ability to achieve a fraction of what you do, it's the knowledge that you and other DIY's pass on via forums (that help those of us that aspire to greater things) that make this and other forums the first port of call when we have a problem.

The caps supplied with the NS1000's were absolutely top quality ones at the time, self-healing too, which is ideal for a monitor and run in quantity to keep ripple down. I'm worried that simply replacing them with designer modern alternatives is going to magically improve things, so I'm keen to see what of any improvement is made.
Unfortunately, I believe that Simon found that the original electrolytic caps in the Yamaha's no longer measured very similarly.
Upgrading caps is fraught with the possibility of changing ESR from the original spec so it can be a bit of a lottery. Sounds like the caps need changing anyway.

I found the old Nichicon spec sheet for the caps, they were utterly shagged when I measured them. ESR was through the roof.
Thanks Simon, at least you're not replacing them blind, which many of us are prone to.

Yeh, I'm still stuck by having to buy caps off the web though. Nick at HFcollective is a decent fella he always matches stuff for me.

That should have been 3.5uF all of them are the same 3.9-4.1uF in value. Which means the mids were seeing 23.8uF instead of 21uF.

I do like them all lined up like this, they were a bugger to remove.

All matched up and ready to be fitted. it won't be the neatest fitment ever, but I can't be arsed to make a pcb mount for them all yet.

A bit of epoxy will have to hold them for now.
20uF Clarity Cap TC + 1uF AUra Teflon for the mids.
2.7uF Clarity Cap ESA for the mids.
1+1+1.5UF Clarity Cap ESA for the tweeter.
Excellent, this is the bit I didn't get round to before the Sound Lab A-3's came along... looking forward to reading about the results! :popcorn:
Interesting that the caps were still measuring high in uF terms. Still around 10% which is good for electrolytics I think :)
Hey Simon, something else you might like to try playing with is the internal damping... I left it quite light.
I never really felt the need to add more, but there's less than half of what was originally inside and your crossover update might well make them a bit more lively.
Cheers...

Closer to 20% high, but it wasn't the capacitance that was the kicker it was ESR. I should have taken a shot before Greg took his Peak Atlas meter back. All the caps were way off spec for ESR some of them were 10x.
All this adds up to a XO that was wildly off spec and with drivers not receiving anything like the signal they should have. If I ever get time I'll sim' the XO with the measured values from the caps (I'll keep one speakers worth just for this purpose).
Mike, the speaker I've done sounds 'better', or at least noticeably different. I'd even be prepared to state that the treble is more extended now. I might give it a spin with the wadding once I'm done fixing them both.

Just what I expected... I would also expect even more 'speed' and possibly a bit more detail too once the new cap's settle in!
Be careful if you remove the drivers to add more filling from the front, they're heavy and awkward to get out and it would be easy to mess up the veneer around the cutouts. The gaskets were replaced with some DIY jobs made from 1.5mm cork sheets... I bought far too much of it and have plenty to spare, so if you need any just lent me know.
I also think I've still got two bin bags full of the 'original' (I don't know if it had been replaced in the past) wadding. As far as I can tell it's just that vile pink fibreglass loft insulation. Just looking at it makes me itch. Horrible stuff!

They don't sound that different Mike. A little more coherent where the mid and treble crossover and the treble is a touch less 'fuzzy'. Like removing a sheet of tissue from over the mid and tweeter.
They feel bloody smooth though...... ;-)

I managed to find a pair of NS1000m's where the owner had 'all' the drive units replaced with NOS parts 3 years ago, and he has the receipt to prove it... WIN.
So I'll be swapping all the drive units over to my speakers and it looks like Ynwan will be the recipient of my current drivers and the incoming XO and cabinets.
I'm rather pleased, minty cabinets and minty drivers- result.
Of course there's the small matter of a 500 mile round trip to collect them- arse....
Hi Simon - just wondering if you were at Scalford back in March and heard the system fronted by NS1000M? I always wanted to have a listen to some but I was disapointed as they sounded a bit hard and shouty with overly dry mid bass and weak low bass. Although other people seemed to be impressed:scratch:. I figure yours don't sound like this, any idea what that is all about?

I heard the NS1000's at Scalford. We, myself and friends, weren't that impressed with their performance. To be honest, I don't think they were well suited to either the amplification, or the CD source they were coupled to. When I tried Simon's Yamaha's in my system, they sounded nothing like the ones at Scalford.

The NS1000M are legendary in the difficulty in choosing partnering kit to get the best out of them.
I had a pair for a while (Stan now has them) and they really didn't do it for me in comparison to some Thiel CS2.3 I had at the time. I am sure there was more to be had, but I just didn't have the patience to try and sort them out!
I had a Lyngdorf 2175 200wpc amp and a lowish powered valve amp (Croft Series 5?), and I am sure others, and none of them could get the Yams under control. The Thiels have a rep as being hard to drive, but they were easypeasy compared to the NS1000M's!
I think Si was showing in another room and may not have escaped - did the amp have a Rogue power supply? Any way, at the time, we thought it sounded like the amp didn't really have them under control. I think there was both a CD and vinyl source - can't remember now (old age I guess). When I tried them at mine - they sounded quite remarkable on the end of my Naim Nap135's.
Si's new Yamys (or is it Yamies..) are sitting on the floor in my hall as I write. They are in stunning condition (well, the drive units are) - except the previous owner appears to have thought it would be a good idea to sand the black paint off the cabinets - and has done a shit job of it - I feel a project coming on...
The TT was I think an Orbe or a Gyrodec. No idea about the power supply. IME a hard sound means the amp is clipping but with it being a valve amp I wouldn't have thought it would sound like that even when clipping.
Well, I've got the Yamaha's in my system now and, to put it simply, they sound absolutely stunning - quite remarkable in every way!
Well, I've got the Yamaha's in my system now and, to put it simply, they sound absolutely stunning - quite remarkable in every way!
What amps are you using , Mark? I've seen your deck already ;)
I use Naim - the pre-amp is quite heavily modified and the power amps are Nap135's (I also use a separate phonostage that is based on the Naim circuit). The whole sounds nothing like the Yamaha's at Scalford.
Forsaking ES14s? Surely not?!
Well, I've heard a lot of speakers over the years and these are the first ones that have given me pause for thought.
Conceptually the Yams and ES14s (wideband driver with no xover) are so very different, I suppose it goes to show that concepts may not be all important but that execution is vital.

Now just the fronts of the cabinets to tidy up and wax and i'm done with the speakers and time to move onto a new pair of stands.
Funnily both the pairs of speakers I bought, one set off Mike and this pair that I picked up last week had drivers wired up out of phase. I wonder how many people out there have a pair where they have wired the tweeters up with normal polarity, (ie as marked) rather than the inverted polarity that the XO dictates?
Yep, one pair had the tweeters wired in reverse polarity and the others had both the mid and tweeter wired in reverse polarity!
Just putting mine back together now.
Edit: And a RYPITA they are being too - entirely because the previous owner saw fit to replace all the drive unit bolts - unfortunately, he used the wrong thread pitch for the mid drivers and did an excellent job of buggering up the T bolts - well done that man!

Difficult to tell from the pics but can you solder continuous wires into the crossover at one end and the drivers at the other or do you have to make use of those connectors shown?
You don't have to use the connectors shown - Simon asked me to fit them to the mid so I did - they can be removed if needed.
The problem with wiring the drivers is that only the - wires are one colour - all the +'s are different colours. Then the bass is marked + and -, which is fine; but the mid isn't marked at all and although the tweeter is marked + and -, it's actually supposed to be wired in reverse.

Guy, the connectors are just there so I can remove the mids easily for when I scrape the fronts down to remove the oil finish and wax them up.

sq225917
13-11-2012, 09:03
There's no markings on the mids as they come from Yamaha, never was. If they are there someone else did them.
Yeah, I couldn't see any factory markings either (I could see ones made by a previous owner though). To be accurate, Simon is the one who discovered the tweeters were wired incorrectly (as it turned out, both sets were wired wrongly!), I noticed the two sets of mids were wired differently.
I'm having are right mare with the mid driver fixings - god knows what thread/pitch the T nuts are. The bolts fitted by a previous owner are standard M5, but the nuts aren't! I'm going to have to make a reinforcing element from 4mm ply for the back!
Could it be that Yam decided out of phase tweeters were better/preferred after they had the xover boards made?
sq225917
13-11-2012, 10:24
It could be that Clive. To be honest when I set them up Sunday night to have a listen I had that horrible sick feeling in the pit of my stomach when I first heard them. The treble was amazingly hard and etched, there was no real soundstage but the really weird thing was the bass- it was gone.
I left them Sunday night and stripped them early yesterday morning and checked everything against the XO schematic and sure enough the tweeters were backwards. I desoldred and resoldered and hey presto. Now I understand the soundstage and treble adding with the mid at crossover to make them spitty but the way the bass was upset is just plain weird.
I wouldn't have expected that effect, but it was night and day different. I'm now very happy. Well apart from the fact that the numpty I bought my M4 bolts off shows them in his listing as being fully threaded, but the ones he shipped came with only 20mm of thread and 20mm of blank shank. The knacker.
From what I remember being told, by someone one here who's owned many, just the mids should be wired out of phase.
At the time I'd been searching t'interweb for ages, and eventually came up with sites/people showing just about every combination possible!... so I took what Mark told me as being as good a source as any!
I was sure there were markings on those mid drivers somewhere or other.... :scratch:
sq225917
13-11-2012, 21:39
Well, he was wrong. It's the tweeters that are wired out of phase, not the mids or bass. I have the original XO Yamaha schematic sat next to me.
Just think you never heard them as Yamaha intended.
Cool.
I got fed up of looking at schematics, I saw too many.... :rolleyes:
Just think you never heard them as Yamaha intended.
Maybe not... but you should have seen how they were wired when I got them. Nasty! :mental:
Hmm...I'm afraid it sounds like you have been told a load of nonsense Mike (not uncommon in the world of hi-fi unfortunately). The mid drivers are absolutely definitely not marked for polarity, but both the tweeter and bass drivers are. Also, I too have looked at a number of wiring diagrams and they all seem to agree that the bass and mid should be wired in positive phase and the tweeter reversed.
If you owned the oak veneered pair before Simon, then the mids and tweeters were wired out of phase to the bass. The pair I have have the original Yamaha wiring and its not that bad - not my biggest concern and certainly not as important as wiring the drivers up with the correct relative polarity.
Been following this thread as a ex ns1000 user and a fan of what they can do,
I bought my 1st pair in the early nineties, used them with quite a few quality solid state amps,
My first valve amp was a German SE amp all of 4 watts, , I never used solid state again with them.
Those speakers with that amp gave me my first taste of realism in a hi if set up.
Since that time hifi has turned into a quest for what I hear as realism..
And I can only blame those yammies, was the start of the slippery slope for me.
I still have a pair parked up at my lads, he's using fostex full range at the moment.

Maybe I'm being overly simplistic, but why the fook couldn't Yamaha make it easy and colour-code (or at least make it obvious by some other method) where the wiring should go? Is that too easy? :)
Moreover, why aren't the speakers 'sorted' and ready for use by the manufacturer, without the necessity for any fiddling by the user, or have this pair been fiddled around with? If I bought a pair of speakers, purported as fully functioning, I'd expect them to be 'plug and play'.
The last thing I'd want to be doing is dicking around inside them, worrying if they were wired in or out of phase correctly!
Or am I missing something here? :scratch:
Marco.
I don't know why Yamaha chose to mark the drive units the way they did - but what I do know is that they thought anybody working on them would know what they are doing.
The Yamaha's go loud without distorting very easily - that coupled with the fact that people often drive them with low powered amps that are driven in to clipping means that tweeters get blown.
Also, as you know, enthusiasts do like to improve their equipment. Simon's pair has had the internal wiring replaced by a previous owner - a neat job too, but that is when they were wired wrongly - not really Yamaha's fault. Mine have had a tweeter replaced and that is why that was wired wrongly. Unfortunately, Yamaha have clearly marked the tweeter and people assume that the red goes to the + and the black to the -, but it doesn't (in this case). To be honest, the X-over schematics are very easy to find on the Internet and the wiring is clearly shown.
Both myself and Si have now looked at the wiring and X-overs of both sets of speakers and studied the circuit schematic. We are confident that they are now correctly wired :) (neither of us are exactly new to this you know ;)).
Indeed, and I'm glad that you've got things sorted and to your satisfaction. However, not everyone can read schematics or has the wherewithal to carry out what you've done, not to mention the inclination, in the first place, to faff about.
I presume that these issues were made clear to you by the person you bought the speakers from?
Anyway, the most important thing is that you're happy with them now. I've always rated the Yammies, so enjoy! :cool:
Marco.

Well quite, I appreciate what you are saying; but with respect to those guys, if they don't have the wherewithal or inclination, they should leave well alone - nothing actually has to be done (assuming they don't break them or feel the wiring must be replaced - which it doesn't particularly).
Edit: What I mean is, they were produced/manufactured with the correct wiring - it's only subsequent modification by owners that has resulted in them being incorrectly wired. This isn't a mod that has to be done to correct a manufacturers error.

Well I'm settling in to life without the Weiss 202, to be honest with the Mdac I'm barely missing it at all. There is however a huge hole in my life where my Su-Prefix used to sit. Life without a phonostage is pretty grim even though I only spin a couple of hours a week on average, the ability not to do so is sorely missed.

On the flip side, I do of course have a box chocker full of components and a new phonostage pcb to build up. I started stuffing and soldering yesterday. I have all the resistor and LED's in place so far and all the Nmos and Pmos mounted on the heatsink for the onboard shunt regulators.

I also have 500 bc327 and bc337 transistors to sort through to find the 4 matched quads that i need for the input stage. I started that process last night and found a good set of 50 327's with suitable Hfe to use. Then i tested the 337's and there's not a single one that I can use to match against the 327's. Trouble is they have to match within a few % and I don't have any within 50 of each other. So it's time to buy some decent grade replacements from a trusted source- group buys, hah!

Maybe I should point out that when I acquired them they had already been rewired (rather badly!) and one had a faulty crossover. Blew a 300B valve, that did! :steam:
Apart from the phase on the mid drivers being incorrect (:rolleyes:) I hope Simon found the wiring done to a reasonably decent standard? Like I said, if you look hard enough around the interweb you can come up with all sorts of schematics... It's the only excuse I have! :lol:

I've just gone through 1300 transistors to find the matches required for the input stage. 4 quads of 327 and 337 within 5% of each other. The guy who bought them for the group buy must have purchased reject match stock. The spread should been 250-600 for Hfe, so you'd expect a bell curve centered around 400, right? Like hell, there were none between 380-440, these had been stripped for matches already- what a f_ck on.

Ok, led's all extricated, now to find some replacements for the blown ones.
Not much I can say on the phonostage. It's a DIYaudio.com group effort from Joachim Gerhard and friends. It's the end product of development on maybe 50 designs over a two year period and about 300 punters took the plunge on the group buy.
With a bit of luck i should get one channel up and running today.

Well done, Simon. That must be a relief. My worst project for not going well initially was the Wireless World Psi Comp 80, a single motherboard computer based on the Zilog Z80 processor. It turned out that a single track was broken on the PCB, a real bugger to find. Great computer, though, when I got it going.

The shunts are dialled down to 18v and the DC offset nulled to SFA.
Now it's time to work on the cases and sleds with the maestro of machining Mr Holterman. I reckon a 3 box jobby, separate psu box with two umbilicals one to each channel in their own box.
Nice one, Simon - I'm sure it'll sound superb when you've finished! :)

Marco, I've done nowt, apart from replacing all my drivers with possibly the last set of complete drivers to be sold in the UK, dated 2003.
Mark has, striped and filled his cabinets, replaced all the captive nuts with new t-bolts, externalised the crossover and removed the L-pads, separated the Xo into 3 parts with pass through for supertweeter at some point, built a whacking great big brace for the back of the bass driver which embeds into the back panel, cut surrounds for tweeters and mids, built gaskets for everything, built a new acrylic back panel to take speakons and provide S-tweeter output and then when he's done with all that he'll wrap them up in a Phenolic resin based laminate and give them new badges.
I guess he'll add more pics as he goes along.
The room measures flatter than a witches tit as it is currently set-up until you get below 50hz where the floorboards are quite active. I might have the spectrums lying round somewhere, it was better than 1db from 50hz to 20khz.
Well if you want your base tighter than a nun's cu.. I suggest you do not vacuum. Just leave those ciggy buts and Heineken cans to mount up.

4/ Three pieces of 15mm thick best quality birch ply being glued together. This will become one of the braces to strengthen the back panel and brace the back of the bass driver.

5/ This shows paper templates that have been glued (with Spray Mount) to the laminated ply. The template has been drawn on a CAD package and printed out. Once glued, the ply has been squared up using a table saw. They are then cut to shape with a band saw and sanded to final dimensions with a disk sander and a bobbin sander.

The braces have now been shaped and a 16mm hole has been drilled with a forstner bit. A laser cutter has been used to cut a 12mm thick MDF plate that will retain the M16 nut. This plate is recessed in to the plywood brace. Here it is being positioned prior to marking out for the rebate (and to check alignment).

7/ The rebate has now been cut with a band saw and the MDF ‘nut retaining plate’ is being glued in to place.

8/ End pieces are being glued in place that will help with alignment within the cabinet.

9/ A point is turned (with a lathe) on to some M16 steel bar – this will be tightened up against the rear of the bass driver; conveniently a small recess already exists in the centre of the rear magnet assembly of the bass driver.

The turned metal bar has a 4mm hole drilled through it to enable easy adjustment (a bar or allen key can be used). The structure will be under compression so the nut does not actually have to be glued in place (a locking nut will also be used but is not pictured here).

Here one of the finished braces is being test fitted inside the cabinet (it is a very close fit) prior to final gluing.

I have laser cut a simple jig to align the brace with the centre of the bass driver. A length of M6 threaded bar is positioned so that it’s point is at the same location as the back of the bass driver.
http://i62.photobucket.com/albums/h90/markemark_2006/Yamaha%20NS-1000M%20Refurbishment/29-01-13bassbracepositioningjig_zpsb244b573.jpg
Here the final gluing of the brace is taking place. The contact surfaces have been dampened and polyurethane wood glue is used to create the bond (it can just be seen starting to foam at the edges of the bond).

Simon,
Was that a Paradise Phono stage you were building?
If so what are your impressions?
Martin
The room measures flatter than a witches tit as it is currently set-up until you get below 50hz where the floorboards are quite active.
I suppose that also means you also get bass tighter than a nuns cun... ?
sq225917
16-02-2013, 11:02
Martin, I'm very impressed with the Paradise, it still currently lives on the floor without any boxes and the wires all over the place yet it is utterly silent in operation. It's just a very good stage, highly dynamic, able to swing from crescendo to diminuendo with aplomb and never gets flustered or leaden. It's most startling ability is the way in which new instruments just jump out at you. Even in a dense musical mix you can clearly pick out any strand and it never seems to get congested even with torturous tracks.
I just hope I don't bugger it up by putting it in three boxes!
Well worth searching out any potential sale in the DIYAUdio.com classifieds, but be prepared to buy a few hundred extra transistors to match. I think there are sound quality gains to be had from matching all of the down to 1%
I suppose that also means you also get bass tighter than a nuns cun... ?
If you're getting bass from a nuns cun.... then, well it's not for me lets say.

So I popped round to Mark's today and took my little camera with me to snap a few pics.
http://farm9.staticflickr.com/8100/8478987587_5d7374626c_c.jpg
This one shows the finish he's got with his laminate, it's super glossy with the finest diffusion pattern to it. It's not a mirror finish, it's more subtle and softening than that. This shot also really catches the effect from that glass edge acrylic.
http://farm9.staticflickr.com/8094/8478988395_37819bbb59_c.jpg
This one nicely catches the contrast in materials between his new mid and tweeter surrounds and the laminate, the closed cell foam provides a textural contrast and really makes the ally driver surrounds 'pop'.
http://farm9.staticflickr.com/8513/8478989569_a9f9c57e34_c.jpg
Here's the back panel with the crossover panel blanking plate fitted. The camera doesn't quite capture it but these are a perfect fit into the recess.
http://farm9.staticflickr.com/8225/8478989991_9cb4d95c3d_c.jpg
Here's a real moment of truth shot as Mark peels back the protective wrap for the first time. The tension, and relief was palpable.
http://farm9.staticflickr.com/8516/8478990415_1f37189928_c.jpg
A little closer up on the crossover plate, plenty of nice detail here, the finish is impeccable.
http://farm9.staticflickr.com/8094/8478990727_e2a4606a99_c.jpg
Ok, enough with the peel and reveal.
http://farm9.staticflickr.com/8238/8480081618_f1f4afaf3e_c.jpg
Extracts from the crossover, mid and bass sections laid out. I think these are soem way from being the final parts, some tinkering to do yet.
http://farm9.staticflickr.com/8106/8478991653_20ee3ac816_c.jpg
Close up of the new badges, these are etched on two sides to give a 3D parallax effect. When you look at them dead on you can see only one line of text, as you shift to the side the depth of the panel becomes apparent and the back lettering is revealed.
http://farm9.staticflickr.com/8109/8480082478_d78bfb476d_c.jpg
Nearly the whole shebang.
http://farm9.staticflickr.com/8109/8478992513_43301641e0_c.jpg
Close up of the brace, that's a beast, that bass driver isn't going anywhere once that is torqued up.
http://farm9.staticflickr.com/8248/8478994249_a364f5cca1_c.jpg
One last shot of the new badges, this one catches the full depth of the panel.
http://farm9.staticflickr.com/8105/8480084430_4314e961af_c.jpg
And that's it for now I'll take soem more once they are finished and back in place. There's still some spraying to be done on the drivers and the edges need a clean.
But bloody hell they do look quite remarkable.
Look superb.
Some fantastic work there.

sq225917
17-02-2013, 15:33
It's Mark's gear not mine.
He did the panels in a specific order so that the front panel went on last and overlaps all the others, the sides went on after the back and overlap them etc etc. So basically there's only the outside edge of the front panel visible from 180 degrees from the front and it's so thin you can't really see it. Each visible edge is dyed after trimming so there's nothing to see, no brown. What you can see in most shots is dust from the routing stuck to the edge of the unpeeled sticky layer.

As long as I remained banned from the Warm I'll not be bringing any gear to show at Scalford. I'm not asking to be let back in again, having two requests ignored is all the answer I need.
Thanks guys - managed to solder the external crossovers together today (except for the L-Pad replacement resistors which I am still waiting to be delivered). The new crossovers are all hard wired with the bass, mid and treble sections all laid out as independent sections. The input allows bi-wiring with the tweeter on one leg and the bass and mid on another. However, the output is wired so that, whilst still electrically separate, the mid and treble use one four core cable to connect to the speakers and the bass uses another. This way, in the future the bass section could be easily disconnected and run actively; the mid and tweeter would then be independently bi-wired.
I've also soldered the internal cabling to the speaker input panels and should have the actual cabinets all wired up by the end of tomorrow.
Will also take some pictures and update the thread.
Oh Man

Ah, the Devil is in the detail :).
As you say, the sound is the most important thing and I wouldn't have gone to this much trouble if I didn't believe the speakers were worth it. The mods fall in to four separate categories; 1/ mechanical/cabinet mods, 2/ electrical mods, 3/ detail improvements, 4/ aesthetic improvement. In total my aim was to address every issue, large or small, that I had with the original design. In future I think it is likely that I will completely rebuild the cabinets as a twin cabinet design made from Corian clad ply/MDF (combo) I was temped to do rebuild the cabinets this time, but I didn't want the speakers to be in pieces for any longer. However, I now have all the CAD and dimensions I need and any future cabinet design/construction can be carried out without taking the speakers to pieces.

I'm glad you like them Si, they have turned out well :). I also think they make a worthwhile improvement, increase focus (will also do you some mid ones).
I'm particularly pleased that I have managed to make them fit without any glue, Velcro etc. - they just push fit on to the heads of the bolts that hold the drive units in place - take about two seconds to fit :D.

Hi Mark
No problem at all we all have our own likes and dislikes and that is what makes for a good discussion.
Again as with any design it is down to the implementation of the finished product itself. As you are well aware their are prime examples of both good and bad!
Point source done correctly is pretty special as can be horn loaded speakers and traditional box bass reflex units (though for different reasons)
In the last five years I have found personally that only speaker companies that manufacture their own drivers have truly got a handle on producing speakers that really do generate realism to a point that you wonder why some manufacturers really bother.
There are always exceptions to the rule, and different people will gravitate towards their own particular style of presentation.
Not having to make too many allowances for driver material, cone excursions, damping, cabinet construction, cross over slopes / orders and components can all be improved and restrictions reduced by using better implemented drivers, whether by the use of superior materials, greater cone suspension, improved voice coil materials, reduced magnetic flux from the coil motors improved wiring etc.
Those speakers include (but not exclusively)
Magico (Q models) a touch hifi for me but a superior speaker without a doubt
Cabasse with their ability to totally disappear and generate an almost anamorphic wrap around sound seamlessly form such small drive units is uncanny. The bigger L'Ocean and Le Sphere are quite something
Vivid a real dark horse in the speaker world, a true sense of effortless unrestrained sound with great tonal quality and a long term satisfaction ownership prospect.
Focal love or hate them they do make some very fine speakers indeed, having owned many of the latest Utopia III models including the Grand's partnered correctly they can generate some sublime sounds.
Take Usher here if imitation is the sincerest for of flattery?
Avantgarde horns is correctly set up can sound intense and very life like and stunning to, though the key is correct set up.
A late entry TAD (Technical audio devices) especially with their CST dual cone Beryllium point source drives simple the best I've heard at reproducing real music.
They are many very good speaker manufacturers thorough out the planet, some are just out on the edge with technology and sound.
I quite agree (in short :).
In truth, although I have heard a number of Cabasse demonstrations, I would hardly say I am au fait with their range.
I've only heard TAD's own speakers a couple of times and would certainly like to hear more.
I've heard a few demonstrations of Vivid's speakers, mist recently one of the Giya range. Unfortunately, at that time, they were playing classical music very quietly - whilst restful, I couldn't say what their performance was like :).
Latest pics? I can't see any new post by you, on this forum, with pics. Dont be teasing us! :)
Umm..sorry Nathan and anyone else thinking the same; the main thread relating to the refurbishment of my speakers can be found here:

They are finished (other than absolute final build of the crossovers, which I will do in a month or two) - am listening to them now....

Sorry all about the quality of the picture above, it was just a quick snap, late at night, taken with my phone.
I will be taking (well Simon, who has a good camera and knows what he is doing, will actually be taking them) lots of photos of the finished project.
I also have a bunch of photographs I took during the final assembly and will be posting them too :).
Great!
I'm interested of the diffraction felts you have surrounding the drivers. Could you describe the material and impact to the sound? Also did you take these in to account when rebuilding the XOs?
It might be interesting to try something similar with my own NS-1000's.. :)
Ah, that's all a bit complicated. First, you cannot compensate, as such, for cabinet diffraction effects within the crossover. Therefore, no adjustment needs to be made. The diffraction diffusers act to make the driver behave more purely in the way the crossover expects.
In addition, these diffusers work both as absorbers (as felt pads do) and, at the same time, as random sound refractors which seek to randomise standing waves and suppress strongly repetitive signals that cause audible coloration/augmentation.
I've been experimenting with this idea for 15 years approximately. I've found that relatively stiff walled foam materials work better than softer materials. The material used in this case is a high density closed cell foam and is precision cut to shape with a laser cutter. The mid ring seeks to randomise reflections at the crossover point to the tweeter. The tweeter has the same aim but with an added aspect of absorption (possible due to its reduced comparative output power).

I think Mika just means was there baffle step correction built into the XO to start off with and did you alter the notch filter applied for this correction. There's no baffle step correction built into the XO, so there was nothing for Mark to adjust.
Here's today's pictures- they do look and sound mighty fine. The bass has defo become that little bit tighter and better damped and the mid and treble is just impeccable.

Stunning quality pictures Si, I can't stop looking at them and I've seen the real thing :).
Absolutely stunning job guys, the finish is frickin' gorgeous. Just one thing missing however, a Do Not Touch sign on top because that finish is going to show off every fingerprint to its full potential... :eyebrows:

Incredible work. Lovely to see such craftsmanship and know how.
I could look at them all day. What's the deal with the 'aux out' on the crossover plate? For adding supertweeters?

Yup, that's Mark's plan.

Have you been able to make any before/after FR measurements either on or off axis to see what has changed?
:clapclapclap:
Well done they look awesome!:)
