There has been quite a few posts in this thread about platter mats, especially for DD turntables. For my SP10mk3 (Krebs 2 mod), I have tried
Boston Mat 1, Micro Seiki CU180 and the TTM Mat with Matching Oil filled clamp (http://www.usaudiomart.com/details/649203862-ttm-mat-2-and-oil-damped-stabilizerweight-combo/). Amongst these 3, the TTM was the best and after I introduced it to Albert Porter, he too thinks it's the best for the Sp10mk3. However, I have found an even better platter mat taht I would like to share with the group. It's Acoustical Systems SDP (http://www.arche-headshell.de/accessoires/sdp-the-sonically-most-effective-upgrade-for-every-turntable/). SDP stands for Special Decoupled Platter. This is not just a mat but an additional platter that decouples and isolates the bearing and spindle from the stylus. While most mats offer some isolationa dn decoupling of the platter, this is the only mat I know that also decouples the spindle. It stands head and shoulders above all the other mats. In fact, for me, the improvement it brought to my SP10Mk3 was greater than the Kreb mods. It's expensive and requires the arm-boards to be raised but it's worth the trouble IMHO. Especially for DD turntables where you have the motor directly connected to the spindle (in most designs though there a few that are decoupled), it makes sense to decouple not only the platter but the spindle from the LP. Hence, SDP probably makes more improvements for DD turntables than Belt drive truntables. FWIW.
Vintage DD turntables. Are we living dangerously?
I have just acquired a 32 year old JVC/Victor TT-101 DD turntable after having its lesser brother, the TT-81 for the last year.
TT-101
This is one of the great DD designs made at a time when the giant Japanese electronics companies like Technics, Denon, JVC/Victor and Pioneer could pour millions of dollars into 'flagship' models to 'enhance' their lower range models which often sold in the millions.
Because of their complexity however.......if they malfunction.....parts are 'unobtanium'....and they often cannot be repaired.

Actually, I don't see this as off-topic. There have been many posts on this thread about mats related to DD turntables.
It's all about wringing the best out of vintage DDs. And I happen to think that the SDP is perfect for DDs and may help to resolve one remaining disadvantage of DDs over belt drives i.e. motor vibrations going up the spindle. That said, I'll be happy to answer any questions you have on the SDP. |
Phew! I'm so glad I moved my SDP platter post to a new discussion. That started a whole new discussion and can of worms. @theophile is correct and I stand corrected. Back to vintage DDs. Anyone tried putting EMI/RFI shield on the platters? I refer to this link for L-O7D: http://www.l-07d.com/tweaks.htm In the link, they use thin mu-metal shield for EMI and ERS paper for RFI shielding. |
