Garth Powell on Why Audioquest does not make AC Regenerators

Interesting interview from a couple weeks ago with Garth Powell of Audioquest who seriously decries the use of AC regenerators with a detailed argument. I’m not qualified to affirm or rebut that argument, but since people debate "conditioners vs. regenerators" here, I’m passing it along for your inspection.

Notice that he doesn't mention ps audio and that ps audio defends its regenerators (as exempt from Garth's critique) in the comments. Not sure how many other regenerators out there beyond ps audio.

My buddy hates ComCrap and prefers ATT. I hate ATT and prefer Comcrap. We can joke about it, to each his own. 
All I know is more people that try ATT around here drop them. But they don't exhibit neurosis.
Tests and members have shown both methods to be equal but different. The rest is sales pitch.

A regenerator is a rectifier that feeds an inverter with a lot of capacitance in between. Many companies make rectifiers and many make inverters. 

Any regenerator can be matched by most full sine wave battery power stations available on the market today … for a fraction of the cost. The difference going from filtered mains to battery was nothing short of dramatic.

I like my niagara 1200 and my Furman pst-8, both designed by Garth Powell. Great quality for not a lot of money.

@mijostyn - I have a similar connection scheme with similar results, low/no noise and great dynamics.  Dedicated lines for two amps and a third dedicated line to an Isoclean filter for all the front-end stuff.  No regenerators, etc.  Maybe I am lucky not to live in a big city or somewhere else with crappy power, but never understood the need for these things.

I owned a Bryston BIT20, and got caught up in the power regeneration concept....and sold the BIT20 for a PS Audio P10 regenerator.  Turns out my power was pretty clean to begin with. Sold the P10 and bought another Bryston BIT20.  
The BIT20 makes a massive improvment to overall system performance.  I didnt have both the Bryston and PS Audio on hand at the same to A/B...but in my brain, the BIT20 is the winner.  And product quality is top notch.
