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.

At 5:something, when he covers his mouth is the best part of the video. Blathering, opinionated idiot. AC regenerator Ir not? Not the point here. 
kingbarbuda,
Can you describe the differences in sound quality between the AQ Niagara 5000 and PSA Power Plant 20?  On the video, Garth mainly talks about the superior power delivery from AQ vs AC regenerator.  But Mike Fremer a few months ago in Stereophile described the gross distortion from his power switch for his house generator.  His AQ Niagara 7000 did little to restore his pure sound, but the PSA Power Plants 20 and 15 did. This implies that for serious wall distortion, AC regeneration is superior.  My priority is not macro power delivery--I want clarity by minimizing low level micro distortion from RFI noise.  Paul McGowan and many users have noted wall AC distortion at 3% or more, which is reduced to 0.1% by the PSA regenerators.  Perhaps Fremer was dealing with very high 10% distortion.  If listeners are in a suburban/rural area, maybe they have very low distortion, so the AC regenerator might do little.
Both products (Niagara and Line/Power regenerator) have their place within the Audiophile community. I have spent time with both offerings.
Each are excellent in a special way. Prospective buyers must audition these products for best outcome. Garth and Paul, respectively, have different disciplines. Trust your own ears.

Happy Listening!
For myself I have owned a  ps audio power plant regenerate. I  now have a Audioquest 5000 conditioner. I was able to A/B both of them. For my electric grid the Audioquest 5000 worked best. 
Appreciate hearing people's experiences. I've watched more than a few of Paul's videos on the regenerator. If I am remembering accurately, he basically says don't use a conditioner -- just use their regenerator. Of course he wants to sell them, but I think his videos are popular because he seems to bring a lot of objective engineering knowledge into his videos. So, as a novice, on the one hand I hear that some conditioners are different or even better than regenerators. On the other hand, I hear Paul saying, the regenerator is the only way to go. The idea of trying both is a fairly onerous experiment, given how much these can cost, how hard to ship, and how hard to try them side by side.
