Power regenerator vs conditioner


If the goal is to improve the sound quality (soundstage, detail, dynamics, etc) and the issue is "noisy" AC, it would seem to me that a power regenerator such as PS Audio P15 would be far superior to a "conditioner" such as a Shunyata Denali or Hydra or Triton.  Is this correct?  Thanks .

@atmasphere  Ralph, what have you heard or have you tried the Puritan products? I put a lot of stock in your views, so I'm asking!

@hilde45  No, I haven't. I took a look at their website. IMO a passive product like this might have some audible effect, but without active circuitry won't regulate the AC line voltage, filter low frequency harmonics (the 5th in particular) and otherwise remove distortion of the AC line waveform. It does look like it would remove spikes and high frequency noise though.
@atmasphere  Thanks. Paul at P.S. Audio has made the case multiple times against passive conditioners for that kind of reason, and because he sells the very expensive regenerator I wasn't sure if his criticism against passive products went against them as a whole kind of product or just the ones out there now. But Puritan is relatively new, I think, so was kind of hoping Paul was wrong about this. It seems that he's not, at least if I am understanding the implications of what you're saying.
Yes- although its possible to use ferro-resonant transformers to regulate line voltage, they also introduce harmonics and they can be pricey too  if one of the lower distortion models. I've really not seen a decent conditioner that didn't have a lot of active circuitry inside.


BTW this is something that has been going on a long time. They were making power conditioners back in the 1950s that were all-tube, using a device called a saturable reactor. You have to imagine that if there was a perceived need 65 years ago that if it could be solved by a glorified power strip that that would have been done and everyone moved on to bigger fish. But here we are in the 21st century and quality power conditioning is still a thing.
For under a $1000 the Audioquest Niagara 1200 made a huge difference in my system. Highly recommended. 

I wasn't expecting much but it had as much or more impact as changing preamps or amps to bring the sound to life.
