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 .

A year ago I got a extra bonus payment from work witch I had not seen coming upfront. I decided to dedicate the whole lot for my new hobby, HiFi. After some back in fourth I decided that I wanted to do something with my power both proctecting my gear and at the same give me clean relieble power. Long story short, I purchased a P12 regenerator. I plugged in all my gear both Parasound JC2, JC5, JC3jr,LuminT2 and SL1200G. The P12 handled all my gear as a walk in the park an the result??? Just immidiate more refined sound, more peace into the recordings and slam in the bottom.end. Total night an day different. Quite fun to see how voltage drops in my street when my neighbours are preparing for dinner with their family, but this does not affect me anymore with the P12. It has a massive coil and capasitors inside (hence weight) ready to feed amp when bottom end is asking for it. I was sceptical myself but Im suremy grandma could even hear the diffrence as it was present right out of the box. Ido live in europe thou so 230volts here witch also make the P12 alot more expensive with currency etc. Still worth every penny
I tried many over the past 15 years and I landed on a newer designed PS Audio regenerator P-12 for my front-end gear and it is the best sounding one I’ve heard from any passive, isolation transformer design like the Furman Reference 20i which I liked a lot. Better than many branded audiophile ones with great marketing. The PS audio allows the music to flow, black background, more body and depth of field as well as imaging. It does what they claim it does, in fact when I run the vacuum on the same line as the PS Audio the meter goes way, way up on incoming noise and distortion at the very top of the range, but the regenerated AC shows only 0.1% distortion with the improvement meter, which shows almost 75 times improvement, I turn off the vacuum and the meters drop back down to 2.5% distortion in, 0.1% out. Voltage in 123 volts most days out a rock-solid 120 volts out.  This unit does as it claims and you can easily hear it. 
JRW-

I learned more in 5 minutes reading your reply than in 5 years
of reading reviews. Thanks!! 

Now who has tried the Shunyata Everest???
JRW - 

I agree with chorus that your response was excellent and very useful. Thank you - sincerely - for sharing your experiences.

The one important question I have for you (so I don't repeat the mistakes others such as you have made and learned from) is could you please name some or all of these "crappier conditioners" that crush the dynamics, etc.

I have read so many times about these issues, but it seems to always be in the context of a positive review or statement about "conditioner A",  which DOESN'T screw up the current flow like others do. And I read this same thing about all of them! So, please do let me know which ones are actually crappy in your view. I will avoid them like COVID!

Thank you. 
Does Millercarbon own a PS Audio Power Plant 20 or is he relying on what he has read? I do own one and it made a huge difference in my system. I had a Niagara 5000 first and My ears liked the PP 20 better.
