The Power Plant Regenerator debate drags on

I’d be curious to try it if I could get a solid assessment of my power. Presently, things are really quiet on my line, but as the saying goes, "You don’t know what you don’t know."

Paul at PS Audio takes ASR seriously. He doesn't agree with them, but he considers various elements in their argument and doesn't merely ridicule them. Good model to follow. 

I recently replaced a Puritan PSM156 with a P15. I agree with @jeffbij that it is an improvement, relaxed and smoother, is a good description. My goal was to have “Sunday night sound” all of the time, and I am pretty close to that with the P15. I should caution though, it was not a religious experience or a night and day difference in my case, but definitely an improvement and worth the investment in my system.

ASR reviews can be useful in certain cases, but they are only one data point. While their measurements might be accurate, I don’t think their conclusion is valid for the Powerplants. 

Never hurts to find out.  You could always pick one up used.  The seem to resell pretty quickly.  In fact, The Music Room  (tmraudio.com) has a couple of P5 units for <$1600 right now. 

For anyone who has the $ to throw at an "if"...

Definitey a YMMV product.

The BEST audiophool $700 I spent was on a used, MIC Power Plant Premier about 8 years ago? 

Sent it back to PS Audio 4 years ago and it should be good for somewhere between 5-10 years?

PP should be in your own setup to see if it does/doesn't do what it's designed to do. I don't hear any negative SQ even with a tube amp plugged in.

The SQ "improvement" is subtle. Plugging in the TV it's noticeable but NOT dramatic-richer color and sharper image quality.

I'd get another PPP,  but PS Audio no longer supports it for repair.
