Any experience using a PS Audio Ultimate Outlet

Thanks David! Just to be sure we are on the same page, I am talking about the Ultimate Outlet AC Conditioner which contains a PS audio power port outlet. This is a balun transformer based unit. The stereophile writeup provides a pretty good description.  Advantages claimed are a reduction of differential and common mode noise at a wider range of frequencies , and no limitation of power. 

Outlets definitely make a difference. I've got three different ones. Also over the years have run three different versions of house wiring to my system. Which is why I say there's way better uses for your money than three dedicated lines, and plugging equipment into expensive outlets isn't such a great way to go. As much improvement as they can make- and some of the good ones from SR really are impressive- the improvement you get from a good power conditioner is even greater. The main caveat being good performing cost-effective outlets are easy to find. Simply buy the best one you can afford from SR. Their conditioners are a big chunk of change so there it gets a little harder as the leap is greater. But then that is what the 30 days is for.

The balun used within the U/O is quite effective at filtering out high frequency and prevents digital hash generated by DAC form contaminating other equipment that is connected to the same AC circuit, therefore, IME, the greatest benefit of the U/O was when used with digital equipment.

Yes, I have used two of those units with the Balum. I did not try them on a dedicated circuit with digital only, but with a subwoofer directly to one unit and one had a power conditioner plugged into it into which my audio system was plugged into.. I had improved sonics using other outlets such as the Furutech and Synergistic Research outlets at these locations. I even had one Balum unit cryo'd to see if it made a difference. It did not. 

Good experiment to do though.
Please report back what you observe.

I have to say, a good outlet definitely made a difference in my system. But I have to ask, how does an outlet “break in”? It is simply a connection point. I can kind of see the concept in wiring being new etc, but given the existing wiring (unless completely rewired) is potentially pretty “old” what happens to the outlet during this “break in” period? Not trying to be flip or anything. I am genuinely interested.
