Andy
New mat arrived today, big beast! I'm going to have a re-read of my old notes with regards the resomat and then compare the two.
Started to make some enquiries about the armpod.
Just listen to the bugger in its own context and see how the music sounds, compared with what you're currently used to (with whatever mat you've been using up until now), and let us know what you think! :)Quote:

I bought the Analouge Studio Crystal Mat on a whim and have very little time to listen to it. Today I had my first proper listen and I'm glad to say that I'm very happy with it. I usually have a few tried and tested tracks that I use to assess the upgrades to my 1210. First impressions would indicate that the mat adds better definition and focus in the bass area. The soundstage appears to have a little more authority and has been brought slightly forward. I would also say that this mat has an ability to unravel complicated pieces of music, this is especially true with bands like Dream Theater. I also noticed additional little drums rolls in Deep Purple's "child in time" from there Made in Japan album. I think this could be a keeper! I'll probably write up more when I get more time and stop playing around with my Quad 405!
Quite an interesting night tonight. I decided to get my Stethoscope out that I borrowed from a friend and have a listen to the plinth on the 1210. I'm pleased to report that I could hear nothing through the plinth (unlike my 301 :(). I really wanted to hear some bearing rumble just to give me the excuse to tweak the plinth. This leads me believe that I don't have to start worrying about adding additional dampening to the plinth and may explain why my deck sounds shit when I start to experiment with the Sorbothane footers (even though some people like them). Additional dampening material probably over dampens the deck. Using a stethoscope is very subjective and unlike reports on the net, you WILL NOT hear complete silence but instead a low grade noise as the diaphragm of the stethoscope scrapes and comes into contact with an objects surface. I spent a good 10 minutes trying to get used to the listening through the stethoscope on various objects including being my 80kg (a piece) tannoy speakers, my 1210 and my 301. The 1210 demonstrated no abnormal noises whilst I tested the top and sides of the plinth.
Hopefully I'll get my review of the new Crystal Glass mat posted here over the day or so with some new pic's.
Andrew,
You might like to try positively 'connecting' the glass matt to the ETP Platter with some vaseline.
I suspect that if you just lay the rigid (I presume it's rigid) glass matt onto the Platter you may not get the optimum result.
The majority of these matts I believe are designed for the lessor sonic quality platters.
Thats going to be very difficult Mike as I don't own the ETP platter :eek: i own the original alum/Cu platter which I thought to be better than your ETP variant. I'm happy with the results of the mat on the Cu top in so far as it has ousted every other mat I've tried including Achromat (5mm 1210) version, resomat, and numerous others. Your probably correct with your thoughts and assumptions with regards my setup, I'm sure things could be done better but I'm more than happy with what I'm hearing currently ;)! I'll be writing some words about it later this weekend with a little luck.Quote:

This has to be the best upgrade I've had in quite some time.
How much does the matt weigh? lt looks to be about 5mm thick!!

I was just going to use your ETP without a mat.
Still deciding on the bearing bass plate, i'll let you know asap.
Hi Andrew.
The use of a clamp is purely optional if you think it improves the sonics then use one. I personally use one and I believe it must improve the reproduction. If only by dint that it firmly clamps the record to the platter.
I personally would not use the type of matt that is mentioned here. but a soft one which allows the record to bed down
and take up any slight discontinuities in flatness. Try the patter on it's own with a clamp first.
Well i have a linn felt mat but i think i like the idea of just using the ETP on its own, after all thats what the label recess is for, a mat defeats this in opinion.
DONT BLOODY THREAD CRAP :steam:
Mike,
yes the the mat is 5mm thick, not quite sure of the weight.

You can buy one from ebay simply by searching in the sound and vision section and typing "tachometer" they range in price from £10-30. I think I paid £25 I could have got it cheaper but decided I wanted one sooner rather than six weeks later from China. I'd always had a nagging doubt that the speed of the 1210 wasn't upto scratch especially with the heavy Mike New Cu+Al platter and a 3Kg glass platter mat. Well after a little faffing the platter span at exactly 33.3 and 45 rpm. :cool:The Tachometer did rely on a reflective strip and the tachometer has to be LEVEL when taking a reading other than that I would heartily recommend spending the £25.
The Mike New Cu+Al platter should work just fine with with Techie. The SP-25 platter is almost as heavy and it uses the exact same motor and circuitry as the SL-1200Mk2. All the ramblings otherwise are just FUD.
There was some question about the ability of my deck to get upto speed. This simple tachometer has given me piece of mind that everything is AOK.
If the motor could not get to controlled speed then I am sure you would hear it, as the speed would "hunt" and produce some horrible sonics!!
as the servo system fights to gain control.
TBH Mike I had faith in the deck but its nice to see that all's well.
Do you have some input on which two upgrades that gave the most effect?
Looks like you'be modified quite extensively. You don't say which tonearm you own. I'd find it difficult to say which mods gave the best effect, but i'd say the bearing, decent power supply and internal regs gave me the best boosts. I notice you've not internally regulated your PCB, perhaps this could be the way to go?Quote:

I think you would benefit from a new arm. The stock technics arm is a fine piece of workmanship but it can be bettered. Lots of people have gone done the Jelco route, some the Rega route ( I could not get on with Rega's). I had the SME V from my Linn days so I brought it over onto the 1210 and have never looked back, some find the SME too analytical so be careful!Quote:

I am tempted to get a spare PCB, so I may look into getting this done.
All this awesome talk of the 1210 is tempting me to buy one and start the upgrading process, I been thinking about it for a while, and as I just finished a complete overhaul of my thorens TD125 mk2 I'm now feeling empty and eager to scratch the itch
Paul no longer does this so you might want to email him and see who he recommends.Quote:

Hi Andy,
I still provide the DIY regulator modules (both external and internal) for the SL1200/SL1210 and the SR3-21, SR5-21/27 and SR7EHD-21/27 are also still available. The retail prices for the SR3, SR5 and SR7 and their respective DC leads have changed but the regulator modules are still the same price. The 10% discount for the SL1200/SL1210 power supplies for Art of Sound forum members still applies.
For those who are interested in power supply and module details see :-
http://theartofsound.net/forum/showt...Power-Supplies.
For those who are not into DIY I can arrange for Paul Hynes Audio Ltd on the UK mainland to provide the power supply upgrades.
Regards
Paul
MASSIVE APOLOGY PAUL . I thought that you'd stopped doing to the regulator mods yourself and had someone on the mainland doing it for you, or was this whilst you had your period of illness?
No need to apologise Andy. I have been rather quiet on the Forum of late, which may have given you the impression that I am no longer active in the industry.
Aside from design consultancy work and providing technical backup and sales liaison to PHA Ltd, I just provide the built and tested regulator modules nowadays. This is usually for DIY enthusiasts but if customers without DIY skills want the modules installed in their SL1200/SL1210, I send the modules to PHA Ltd, and they install them for customers. PHA also provide the SR3, SR5 and SR7 power supplies for a wide variety of audio applications in high end HiFi and Pro Audio.
Whilst I, and family members, have had a few health issues to deal with along the way, the transfer of power supply production to PHA Ltd was not specifically for this reason. It has mainly been done to release me from production and administration duties, so I can return to R&D and preparation of the many designs I have had to set aside over the last 8 years, due to lack of time caused by an overflowing order book. I will post details of each design release in the PHD and PHA AoS forum trade threads as they occur.
Regards
Paul

Resurrection from the past! I've not done much with the 1210 in over a year but I've ordered a bloody big bamboo IKEA chopping board for my Lenco 75 on the strength of how it increased the microdynamics of virtually every slab of vinyl I tried. So, I'm going to be doing some experimenting with the 1210 when I get a little time over the next few weeks. Watch this space!
Is it worth encasing the bearing in marine resin to reduce vibration? Certianly something to think about.
Are you refering to my Bearing Andrew??
Who else, mikey!
Andrew you are a man of taste!!
I really honestly do not think that embedding the Bearing in marine resin is going to improve the sonics by any measurable or realisable amount.
Especially if you have my Bearing Base Plate epoxied to the chassis.
Also this would be a one-way process.
I've been listening to the subtle differences of chopping boards sitting under my 1210 and I have to say that I'm hearing some nice subtle improvements for a potential £30 upgrade. I hope to do some more listening over the next few days to confirm my findings.
Try inserting an inner tube for a bicycle between your chopping board and the support
then vary the amount you pump it up.
By the way, what has happened to Marco my emails get bounced back to me saying invalid address,
Send him a pm on here Mike.Quote:

Hi MArco,
I sent 3 emails and they all got bounced back as being an invalid address.
I thought that perhaps you had retired to your chateau in the south of France.
Lol... Sadly not. Must be a problem at your end mate, as I've not had anyone else tell me of such issues. I'll send you an email and you can respond to that :)
Marco.
OK, to get this thread back on track :rolleyes:. The 1210 now has a new tweak in the form of the Ikea
http://www.ikea.com/gb/en/products/c...la%7C%7C%7C%7C
I've had several days evaluating now and I'm pleased to say that it provides a very nice upgrade for the cost and I would suggest it offers true SPPVFM.
Just a quick pciture of the deck as it now stands in Feb 2017. I have also written a small review which can be found here.
Attachment 19242
The board is a perfect fit for the footprint of the 1210. Now I have a very nice reference tonearm cable from Yannis Tome to review and assess on the 1210, the 420 litz. :eyebrows:
Yes, I'm looking forward to your review of the 420 Litz Andy. Yannis's own overview of it here http://theartofsound.net/forum/showt...rm-cable/page2 gives the foundation of what looks like a seriously good tonearm cable.Quote:

Btw - remind us of what one costs ?
I did originally intend to write that review but never got chance. :o The 420 has been sitting on my 301 for the last ?year maybe producing lovely sounds so I guess it's time to swap them over and have a listen. I think the cost was about £700.
