Best platter mat, especially for DD turntables

There has been quite a bit of posts about platter mats and I wanted to add my experiences. I have posted this on the vintage DD thread but have been requested to move this into a new discussion, so here it is.

For my Technics 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/). Among these 3 mats, 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 that 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 isolation and 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 turntables. 
Here is how the SDP is different from other mats. What is not obvious form the pictures is that the SDP mat is thicker than the original spindle height. Hence it sits over the original spindle completely and has its own precision spindle to guide the LP and clamp/s onto the SDP. In other words, the original spindle is buried inside the SDP. Underneath the SDP are soft vibration absorbing gel packs which interfaces between original platter and SDP. This allows the SDP to absorb vibrations from the original platter. The mass of the SDP also acts as a damper for any vibrations from the original spindle. 

The net effect is that the noise floor drops further and I can hear more detail, resolution, separation and space. Very startling improvements.  FWIW.

It is obvious that the TT manufacturers have no idea how to

produce an, say, decent mat. What they overlooked is to

consult the amateurs from different forums and learn how this

should be done. The ''mat mistery'' is easy to understand. We

all want incredible impovements for cheap. Considering  the

present TT prices not a bad idea at all. The only thing one need

is to believe to have heard ''incredible improvement'' in sound.

Even the LP 12 owners will get again  a new ''improved '' TT

with a new mat. But which one?

Well those damn variables. As some honest economist confessed:

''I am sorry but there are to too many variables. We can predict the

past but not the future''. I wrestled with some of them in connection

with my SP10 (aka SL 1000 Mk 2) with Obsidian plinth. Among many

mats I have chosen for the SAEC SS 300. Alas I has no idea that

 Lew has those as spare in his closet. So I paid the full price.

However the AT 636 pneumatic footers made much more

improvement to my SP 10 than any of those mats. So while all those

variables are marked in the same way (x,y,z) they are not equal. So,

I would say : ''check first your footers''.
