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.
