I had been adding Omega E mats one-by-one over several months and enjoying each improvement the four mats brought. This week, I placed a mega-bundle of four more E mats all at once to further shield my CDP (four mats now) and to fully cover underneath the mono blocks (two each). The improvements in detail and soundstage began to emerge in a matter of even one hour.
I was then inspired to pull together every source of EMI I could think of (there's more) and post it above (see my post #400). Like many, I've been aware that cables and cords do make good antennas and need some shielding from EMI----did that, job done, forgot about it.
The pervasiveness of EMI in our homes and systems has been proven by Tim Mrock, then innovator of the E mats and cards, to have much, much more of a degrading effect on our audio/visual systems than previously recognized. Tim has successfully demonstrated the overwhelming presence and effects of EMI by inventing the device that effectively shields it out of our systems.
