Wow! I was listening to the 1st pressing of Jimmy Page/Robert Plant "No Quarter", (which is an excellent sounding lp), and since it was in need of flattening, I put the Stillpoints LP isolator onto the top of my McCormack DNA 225 (Platinum) that is sitting inside (on the bottom shelf) of a Solidsteel 5.2 rack, the amp's shelf, which is a BDR, "shelf-for-the source" platform that is itself, sitting on three original Stillpoints isolators, the amp is isolated more by Symposium Rollerblock Jrs. w/ ceramic ball upgrade. Whew!
Now, while the lp was playing, and the lp isolator was not in use, I put it on top of the amp and, WOW!, the dynamics were much improved, it almost seemed as if the volume was increased, I feel that so much hash was removed that I was hearing what is really on this lp!
