A lot of hype about PS Audio, deservedly so ?

PS Audio's production quality is excellent as manufacturing is now happening in Boulder, CO rather than in China as previous PS lines were.  Example of the benefit:  My China manufactured Premier Power Plant was not as robustly built as my present P5 Power Plant. The dynamic response of my system with the P5 is spectacular.  Didn't realize how much I was missing until I traded up to the P5.

You might consider going to PS Audio's website and sign up for Paul's Posts or watch several of his daily videos about all topics audio.  You will get a good sense for where Paul McGowan is coming from and why he approaches products the way he does.

I don't know the answer to your question but I do know that PS Audio will stand behind their products and are available for questions on the phone etc.

Good point @lak.
 
PS Audio will and does stand behind their products and even, under appropriate circumstances, beyond the warranty period.  One thing I am pretty well convinced about;  Paul McGowan wants to make a positive difference in the audio industry and cares about the satisfaction of his customers.

Amen!
