Spectron,
As you must know "your mileage may vary..." Some of the posters claim not to hear anything, and based on their experience, they may be right! The simple fact is they have not heard the new Evolution Signature mat, which is a SIGNIFICANT improvement over Ron's previous designs. The other fact is that not everyone' systems are that high in their resolution.
I have two audio systems. One in a dedicated purpose built and professionally acoustically treated listening room with a dedicated separate electric feed that houses an ultra high end system that has been carefully matched and assembled over the years. It's total price is in the stratosphere - well into the six digits. I will admit that in the context of this laboratory grade playback system the improvements are exactly as I had described them above.
The other system is in my basement workshop. That system is basically Audio Research electronics throughput with Magnepan loudspeakers, Shunyata Triton and King Cobra CX power feeding the system on dedicated lines, with Transparent Audio cabling. This is the much more down to earth system that is closer to what most guys will be using. There are improvements to this system, but nowhere near on the level as those on my reference system in my sound room. Even in the context of this more modest system, there are the gains in both the detail and image focus that you mention and is well worth the $200.00, but again in the context of my reference system the gains are MUCH more apparent, as I think the "sonic microscope" is set to a higher power of resolution in that room.
For fun try burning a couple of your best disks into your computer using the mat and them burning copies from the computer again using the mat. I think that you will be astounded with what you hear. Yes, the copy sounds better than the original, especially with image, sense of venue and space, as well as an analogue sense of ease. As you know, the new disk is not much thicker than two sheets of paper, so it will easily load into any player or computer without any problems. It would be instructive for others if your reported your finding of this on this thread! Have fun!!!
