PsAudio 300?

Concur with all of the above. I have both the UO and the P300 with Multiwave, and the P300 is certainly the more dramatic improvement. The multiwave makes a big difference, too. Occasionally I have forgotten and left my P300 in normal 60 cycle mode, and after a short while listening, I can tell something's nit quite right.

You won't regret adding the P300 to your system - I wouldn't be without it!

I have both the 300 and the 600 in separate systems and have been both surprised and impressed with the results. Impressions are similar to those described above. One version will be a must in my systems now...

Just let me know if you have any questions about the systems I use them in, etc or check older threads.

I have 2 of them and would not be with out them. One of my best buys! PS Audio will give you a free in home trial period for 30 days(minus shipping). You cant beat that. Do yourself a favor and try them. And NO, I do not work for PS Audio. But I will say thet Paul and PS Audio are one of the best I have ever delt with! Good Luck to You!

I hate to rain down on your parade, but I'd suggest caution. I had PS300 w/Multi and wasn't too impressed. It did lower the noise floor but the music was sapped of its life and dynamism. I had it burned in for almost four weeks, and hooked all my sources to it. I called PS Audio and their suggestion was that I would have to use a PS Lab cable between the wall and PS300. I was using a Zu Cable Birth in that position, which was the best PC I had, but a PS Lab cable was at least $250-300, which would raise the price of PS300 over what I wanted to spend. So in the end I decided it wasn't worth the price and returned it.

I'm not knocking down PS300 necessarily, as I haven't had much success with power tweaks in general. Maybe the power I'm getting is clean enough, as I live out in the middle of corn field. :) But get a used one and see if you like it. If not, you would be able to sell it without taking much hit.

I'm using a P300 to supply everything in the system except the two amps. There was an immediate and obvious improvement as soon as it was plugged in. It's my belief we suffer from poor quality electricity and I believe the P300 helps there, a lot. I don't have the fan. The unit runs hot to the touch but I'm not pulling anywhere near its capacity. I've experimented with the multiwave feature as well as pushing the voltage up and down. I find neither of these features makes any audible difference at all. Some multiwave settings cause the transformer in the DAC to hum. The only real negative to using it is its own transformer hum. Its not too loud but its a definite minus. I'm experimenting with resonance control now to see if it can be minimized. Last, its great protection for the system. We have frequent brown outs. When the line voltage sags, the P300 cuts out and protects everything. Its worth it for that alone.
