I have one and have used it in conjunction with a PS Audio mini-lab cable to my power amp. The other outlet feeds a Monster HT2500. I got good results with this combo when I used it with my Musical Fidelity A300. The combo definitely lowered the noise floor and increased the dynamic thrust of the system. It doesn't seem as noticeable with the Bryston power amp I use now but I believe its a good investment anyway.
PS Audio's Ultimate Outlet
Anybody out there have personal experience with this baby? It sounds good on paper. I have their Juice Bar and am happy with it. Hooking up with their outlet seems like the most cost effective thing to do. At least that's what they say. Anyone out there have the first hand scoop?
