I had a UO HC when my system was cdp-pre-amp and it seemed to be ok with the preamp, but not the amp or cdp. When I changed to a cdp-passive-amp I could hear substantial degradation of the sound on either the amp or cdp. The transparency of the passive made it very easy to hear the sound was better without the Ultimate Outlet HC.
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?
