While I think the AMD products have similar goals to achieve greater noise shielding and I don't mean to knock them but they don't come anywhere near as close to the level of the Perfect Path products.
I have quite a few of the AMD products that I purchased a couple of years ago and their effect is very negligible compared to that of the E-Mats and Omega cards.....and I haven't even heard the full of affect of them yet. The affect of the Perfect Path Technologies products is a clear and substantial improvement to sound quality. When I removed the AMD products ( six plug ins, two passive units and the wrap around the electrical service pipe I didn't notice any difference in sound and the overwhelming presence of the PPT products most likely caused that. I'm not about to remove the E-Mat and 8 Omega cards to how much the sound diminishes as I'm not willing to give up the benefits they've added to my system! Whatever Tim does to make his products so effective is very impressive and I look forward to adding more of his products to the mix.
