The whole system including the excellent Williams Audio DAC (Tubehunter) and Tube Distinctions 30 Watt Push/Pull Copper amp, one of four in existence. Marco also has one.

Isn't this just gorgeous! (Well, I like it anyway and it sounds even better than it looks.) Note also the AOS/Tube Distintions I & E linear PSU feeding the Bel Canto CD transport in the background on its own dedicated stand of course - PSU are microphonic!

I am very pleased with this system. I'm just waiting for my VDH digital interconnect to arrive then I'll have a very detailed, involving and insightful system that captures the passion and subtlety of musical performances.
Looking really good, Steve. Welcome to the Copper amp owners club! :)
I can see what you mean by the finish on the black transformer covers - it shows on the last photograph... I like it too; I'd definitely leave them as they are, as it is part of the originality of the amp and what defines it, aesthetically, from mine.
Pity I missed hearing your new amp the other day, but knowing your system and what the Copper amp does, I can well imagine the superb sound you're getting at the moment! You've now got a pre and power amp for life, as to even attempt to better it, you'd have to spend tens of thousands of pounds... So look after both of them!
I'd just like to offer a quick word on the version of Duncan's DAC you've got, as I heard it along with the rest of your system the other day...
Dunc, mate, I've no idea what you've got against op-amps because quite honestly that DAC you've built for Steve is one of the best I've ever heard, so much so that I'll no longer have to bother bringing the Sony down to the Scalford hall bake-off/show in March, where we're going to be demonstrating a system comprising of various components belonging to the admin and management team of AoS.
I'm not saying that it's better than the Sony (we've yet to do the comparison, and I suspect it lacks a little low-end grunt compared to the DAS-R1), but it utterly transforms Steve's Bel Canto CDP from something I couldn't listen to for very long, into something that I'd have great pleasure listening to for hours and hours (I've always seen the Bel Canto CDP as essentially a top-notch transport with a 'less than top-notch' DAC)!
The 'Williams Audio' DAC has masses of resolving power, and an extremely low noise floor, so that one can hear right into the musical mix, unearthing subtle nuances and vocal inflections that previously the Bel Canto's built-in DAC either missed or imbued with a coloration which rendered it as rather indistinct and somewhat indefinable. The significantly improved resolution has the effect of giving all types of music almost tangible realism and believability.
Furthermore, the 'Williams Audio' DAC has clarity and dynamics to die for, and virtually a complete absence of perceived sonic signature, yet it doesn't in any way sound cool or clinical; bass is deep and tight, but also rhythmic and tuneful, and the mid and top-end are wide-open, giving voices and instruments an expressive intelligibility, but is also sweet and completely lacking in edge or 'grain', so all-in-all music is simply showcased to maximum effect with minimal perceived 'interference' from the control electronics.
Basically, Dunc, you've built Steve a belting DAC, which I suspect is easily as good as the valve-based version Ian and you use (and perhaps in some ways better) - a comparison would certainly be most interesting (including one against my DAS-R1)! A DAC shoot-out between the three is something that we'll need to organise in future :cool:
All you need now, Steve, is a big pair of Tannoys (and a modified SL-1210 and music server) and you'll have finally arrived!! :gig:
Marco.

Wow that copper amp looks bloody lovely Steve well done.
I'm actually sitting here feelin a bit envious of that thinkin it could have been mine:doh:.
Never mind eh maybe i'll just have get Anthony to build me one some day.
All the best with it Steve dont forget to bring it here for a listen sometime.

Well done indeed Steve, very jelous but all the best in your new adventure, i had to be sensible and not go down that ever so tempting upgrade route at the moment, my money has to be spent on more disserving causes at the moment in this funny old economic climate, but heyho chin up and i won't let the bastards gring me down:)

Hi Steve,
It looks good and many are going green with envy!
I like the look of this copper chassis business, but I have to ask, is it lacquered or something, or will it too, go green over time? (Absolutely not a criticism, just interest & curiousity). Maybe Anthony would be the best person to answer?
I can answer that, Chris... No, the chassis is made from a solid sheet of copper - not cheap (especially now), but I think you'll agree it looks stunning!
I think (and Anthony can correct me here) that just to build the chassis alone now would cost about £800.
The only lacquered bits are on the transformer covers on mine (No 4 shown above); Steve's are sexy black :)
Marco.
So you need to keep polishing it then?
Yep. Just looking at it marks it! :eyebrows:
Nah it's not quite as bad as that, but every time I move the amp for any reason, it gets a good polish, otherwise the fingermarks ruin the finish.
It also weighs 40kg; not as heavy as a Mr Liang, I don't think, but signficantly heavy for a P/P design!
Marco.
Steve Toy
20-11-2009, 10:27
Yes they do need to be polished from time to time. Bear in mind though that these amps pictured were both built in the late nineties and neither of them have turned green.
Alex,
What system are you planning to run through the Heco 700s? They are a very insightful speaker but they are also very revealing with it. They tell me exactly what my system is doing as well as what the music is doing.
Such honesty can be quite brutal.
Yes they do need to be polished from time to time.
Nothing wrong with that. :)

Marco.
Yup, I realised that it was made from solid copper, but what I meant was, is it then sealed from the air with some sort of coating to prevent it going green, or do you have to give it a once over with the old Brasso?
I suppose a verdigris amp would be cool too, though!
My parents have a huge, intricately cut & engraved copper topped coffee table which we brought back from our time in Pakistan - I remember when I was a kid, the whole family getting round it every now & then to give it the Brasso treatment.
I'd worry about cleaning an amp like that because the gunk that you raise gets everywhere if you're not careful.
Yes they do need to be polished from time to time. Bear in mind though that these amps pictured were both built in the late nineties and neither of them have turned green.
Indeed. That's because the previous and current owners have looked after them. It's the type of amp you take pride in owning, and of course Anthony's a bit fussy as to whom he sells them to ;)
So I've no idea why he let a couple of dafties like us have them! :lolsign:
Mine was originally built for a London recording studio, and still has the exact same GEC (KT88) output valves fitted since 1997, which test 100% fine (and sound superb) after goodness knows how many thousands of hours of use!!
What are the chances of modern valves lasting that long??
They just don't make 'em like they used to...
Marco.

Anthony would be the one to answer that, but like Steve says, both our amps were built in the late 90s and neither has turned green.
I just give mine a once over with Brasso whenever my fingers have been in contact accidentally with the copper areas from lifting the amp, which is only very occasionally, so I suspect that the chassis must have been sealed or treated in some way :)

Either have the copper parts lacquered, or wear lint free cotton gloves when moving the amp. (You ought to have a pair of these gloves to wear when you change valves. ;))
Regards
I have all sorts of gloves for all sorts of purposes, dahling! :eyebrows: :eyebrows:
Marco.
Marco,
I wasn't joking when I suggested the use of cotton gloves when handling valves. It's best to avoid getting greasy fingermarks on the glass envelope if you want to maximise the valve's lifetime; especially important if you do a lot of 'tube rolling' with expensive valves.
Regards
Oh I know you weren't joking, shweety - I just couldn't help using it as an excuse to make reference to something kinky! :eyebrows:

hi all,
thanks for your kind comments, first of all, marco, yours is number 3, not 4!:doh:
they are all laquerd inside to prevent them corroding, but the outsides were left bare, reason being i like copper when it goes that lovely dark rose colour!
as marco has already stated, all four of these amps were made in the mid to late 90's, no 1 is somewhere in honk kong, no 2 mr toy now has, no 3 marco has, and no 4 is somewhere in reading, or there abouts.
the first one was of course my own, the second was originaly built for a customer in wales, and no 3 and no 4 were built as a pair,originaly to be used for studio monitoring.
hope this helps.

Steve Toy
20-11-2009, 13:53
I've always know that mine was built earlier than Marco's so there must have been some confusion.
Hamish, yours was modified to be based on the Copper amps and shares the distinctive traits of bass grip, involvement and dynamics not normally associated with valves.
Your amp was featured at Chesterfest, Owston and Scalford all alongside Marco's Copper amp. The latter is perhaps a touch more refined but a number of people expressed a preference for the clarity and fun factor of your amp. It is also very much a Tube Distinctions amp in that the resemblance to the Puresound A30 is only in appearance.

Don't tell Marco, but I do too... but I wouldn't turn either down!
Steve, I haven't really got a plan for my system (a thread I keep meaning to start) but I just am really drawn to the Celan's, and I suspect it is inevitable I will end up with glowy things if I stick around here long enough! The Garrard 401 will be re-plinthed and a new cartridge added as the main front end, I suspect. The rest of it all undecided - all part of the fun though, mulling over the options, isn't it?!

They certainly look very nice indeed, i have a fettish for Chromium plating so would have the copper chrome plated..I think the best thing with the guys who like Copper is to have it clear anodised which would give a non tarnishable finish in a satin copper lustre.

P.S I also like the black covers on Steve's amp. It helps break up the rather imposing 'vision of copper', but I'll be keeping my amp 'as is' :)

Clean it with Xylene before brasso, but no fags in your gob & a mask while doing so, will give a better finish.

The system now has its VDH digital interconnect fitted. The DAC seems to have improved with even more burn-in and it's all making for very enjoyable music listening with all the subtlety and emotion of the music being laid bare.
The power amp is one incredibly finessed beast. It doesn't miss a trick and yet it reproduces it all with such grace and ease. It has to be one of the finest amplifiers ever made regardless of cost. Anthony Matthews is indeed very talented.

So did the digital cable arrive as 0.5m or 0.8m, and can you describe exactly what difference it has made, sonically?

2) The difference can range from subtle to very noticeable. That quacky mid could be due to an i/c touching a wall.

Mike, Naim decouple the panel on the rear of their kit where the sockets are. They also decouple the plug from the cable on their expensive mains lead. This makes an audible difference that is similar to and almost as dramatic as going to active crossovers with their amplification.
I'm not lying.
Is your system sufficiently revealing to show up these nuances? :p
Do you use Naim then? :eyebrows:
And, prey tell, what 'decoupling' do you have on that loverly copper amp? ;)

hi chris,
the power supply uses a single choke for the raw DC, then its split into two seperate HTsupplies for each channel.

The effect won't be heard via headphones because they won't be chucking the energy out into the room that is then absorbed by the walls.

There is benefit to be derived from moving them away from skirting boards/walls.

Um & a piece of shit aswell, thats a cheap wall socket in the MK range. MK 'Logic' are the ones & for god sake why switches, they add impedance to the line, a more noticable effect than a cable touching the wall?
;)
Haha... He's got you there, Steve! :eyebrows:
Andre, I'm afraid that's one area of Steve's system set-up which still requires some work - a separate mains spur, like mine, supplied from a dedicated CU. He could then fit a better quality wall socket on the end...
Btw, the single 13A versions of the sockets you suggest shown in your pic are even better (and cheaper). As he's got a quality mains distribution block, he doesn't need a double wall socket, too - the other side lies unused, and so is unnecessary :)
Actually, thinking about it, a cheap and simple upgrade would be to change the wall socket first. I'm sure he'd hear the effect.
Marco.
Rare Bird
25-11-2009, 02:03
If he's prepared to rip out the old double back box & plaster up the remaing hole in the wall yes it's easy enough..When he's done that, he wants to scrap his amplifier power switch & associated AC fuse & fit an ETA circuit breaker/come power switch, this does away with an AC fuse & the extra wire & contacts associated with original switch/fuse which i'm sorry to say adds extra unessisary impedance to the supply.
These items.. will fit in the old fuse holder cut out. The 5A one has a 0.05 Ohm internal resistance. compare that to what you'll be replacing

all sound advice!!! apart from doing away with the mains switch on the amp as they are very hefty, [10 amp] low impedance types :)

Thanks but the idea is to do away with the AC fuse & extra contacts/wiring.Surely you fitted a fuse holder to the chassis? just utilise the cutout.. 10amp even better they have 0.02 Ohm internal resistance..He could leave your original switch just disconnect it.These ETA breaker/switches are far more sensitive to faults on the power line aswell & obviously sound better.
Looking nice:eyebrows:
So how about some details about the dac? I asked once before on the diy thread, maybe it was missed:) a pic of the top would be good if the pcb can be seen, you know I'm a saddo with dacs:lol:
