Power conditioners and power regeneration

There are so many different options on this subject it’s unbelievable. But in the meantime it seems to me that between two companies that I’m comparing, they seem to do the same thing with power conditioning, and as far as I can tell there is no audible difference. Comparing two different conditioners, the elite 20 pfi and the aq pq2. On the other hand, I’ve heard that power regeneration is good, but it also can generate noise. Besides plugging into the wall, which I know works great, I still would like some protection to my amplifiers against brown out or surges. Has anyone else experienced any difference with these 2 products?

I only use Furman for my audio gear for surge protection.  I use a Furman voltage regulator upstream of the surge protection.  This gives me tight (5 VAC) voltage control along with excellent surge protection without the AC noise or expense of the regenerators.

Power regeneration is generally expensive and runs hot. Some folks like the results, others don't.

This reviewer has used both regeneration and filtration. You might find it interesting.

Lots of sour grapes on regeneration. I have the PS Audio P10 and it has none of the problems that those selling other "conditioners" report.  When you're good enough that people have to make stuff up to defame you, then you must be doing something right.

My power into my house is 4% THD with chopped sign waves.   The output from my P10 is a perfect sine wave with 0.1% THD.

It sits there cool as a cucumber year after year.

I'm not saying there are no other "conditioners" that work but I know this one does and I know a lot of the "conditioners" on the market limit current and do more harm than good.
