I still use a Furman ITRef20i for all my audio equipment and an Elite 15PF for my HDTV DLP, Lumagen Scaler, HDTV Receiver, etc....both units are permanent part of my system now as their effects are both widespread and excellent on the quality of the system as a whole. As to any marketing claim that by a catalog that something would effectively double the power of an amp, I'd suggest you call Furman and get the tangible benefits as they would explain them. You won't go wrong with Furman.
