PS Audio's Ultimate Outlet

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.

I recently added an Ultimate Outlet for my amps. I think I heard an improvement (which probably means I couldn't but I didn't want to admit it!). I purchased it as one of several AC mods including Quiet Lines, a Wattgate outlet and a Monster 1000 (for the front end). I felt the same about each on of these individually--little if any improvement. However, when I combined them all the synergy was incredible; perhaps a 20% improvement in the sound. I now firmly believe in AC tweaks but the process does seem to involve a lot of experimentation and Brownian motion. Good luck.

I can hardly believe we are all talking about the same thing here.
I bought it to use on my amplifiers as the PS 600 was not up for the task of both front end and amplification.On its own I found a much more quiet refined sound adding natural full timber to the music,the problem was the sound stage shrunk as a trade off.I added PS Audio lab cables before and after the UO .The sound stage problem was completely reversed while gaining much more in the other areas including resolution and bass authority and depth ,I then went a step further and added a second set up one for each mono block,with equally stagering results.
Conclusion is if you plan on using the UO on there own you might as well use it on your TV.Great results can also be found with the mini lab feeding the UO and another to the power amp.The same results ocured using different amps and in my friend set up as well .These changes were not small ,I plan on adding one more UO to feed my PS 600 ,my friend has been done this with proven results,once again with proper power cords.The Uo power cord as a unit are a better bargin and performance for this,but you would be limited for trying other PC in the future.

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.
