VPI TNT record clamp

I have replaced the one-piece delrin clamp on my Aries with the BDR clamp. I like the results a great deal. My impression is that I'm hearing fewer of the intrusive noises inherent in the stylus tracing the groove. There is less groove echo, cymbal splatter, and ringing with high energy horns and vocals. I feel like I'm hearing more of what is recorded. Every aspect of the presentation is affected.

I have heard a similar set up with the Shun Mook clamp which is made from ebony and is very dense and heavy. Its effect is very impressive, but I am unable to directly compare it to the BDR because the systems in which the turntables were operating sound very different. This clamp is also hideously expensive and very difficult to find.

I had the BDR clamp on my early model TNT, thought it was fine, then tried a Ringmat and was amazed at the (to me) improvement in clarity, focus, and dynamics, with no downside I could detect. I eventually upgraded to the graphite Boston Audio Mat I and have no desire to return to clamps of any kind. Obviously, YMMV.

Dopogue, I take that when you use the Boston mat you don't use a clamp. Can you use a clamp or is it designed to use without one.
Thanks
