Here is my take on the eMat. I have a fairly nice system, have what I consider decent but not extravagant anything, nice enough speaker cables, interconnects and aftermarket power cables. I can hear changes when made to my system easy enough. Other than that just mentioned I have never purchased one tweak. I happened to obtain a few eMats free from a friend. So no skin in the game one way or the other.
I put the mats in the cover of my electric panel and on or under all major components (not speakers). I also made one other minor change to my system I cannot remember. I have to say that at the time I noticed a nice identifiable improvement in the sound of my system. But because of the other non eMat related change there is always that question in my mind how much improvement there would have been without it. Personally I attribute it all to the eMats but truly have no idea how.
