I suggest calling PS Audio and discussing it with them, describing all of the details, as you did in your post. They are one of the most helpful and customer oriented companies around, and are usually willing to do just about anything to help you fix the problem.
From some of the above posts it sounds like your problem may be from incompatibility with some of your power cords, etc. Or a slight chance of a defect in the PPP, although not likely.
Also try some of the different settings of the PPP, accessed from the remote, including having all of your components turned on (not running) and activate the "clean wave" function. This will "degauss" all of the connected magnetics.
I have a PPP plugged into a dedicated 20A circuit, and use a variety of power cords, depending on the components (JPS Labs Digital AC for SACD player, etc.) and the difference in sound quality after hooking up the PPP is amazing.
