PS Audio's Ultimate Outlet

because it adversely affects the sound.

I currently own one for my Pre/amp and am ordering another for my cd player. I will admit the sonic improvements are subtle. However, it does provide surge protection and unlike many other similar products it doesn't seem to compress dynamics.

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.

Another subjective evaluation of a system/power source dependent component. In my system, the background around the notes became more black with a single unit. I added a second unit, one for preamp and amp and the second for CD transport and DAC, and the high end became much more clear.

Commetns on UO HC:

Good results with DAC and pre, avoid it with amps.

Tried it on a Denon 5700 receiver, and it gave it sounded much better (again, not so with stand-alone amps).

Less noticeable if you go to dedicated power lines, but still nice (I have the DAC plugged into it).

I'll probably switch to a 20 amp IEC on it and see what that does.
