Power regeneration - good idea? PS audio?

I have a P12 for the stereo stack (Oppomod 203, PSA DSdac, BHK pre, Pink Faun 2.16x, Cisco switch) and 2x P20's running my BHK 300 amps and SVS 3000 subs. Very happy with the performance increase with each one.

“So at the end of it all what is the point of this PS audio regenerator?”

If like me where night/day AC voltage irregularity/variance coming in is significant enough (>5%?), it matters a lot (soundwise), more their stabilizing capability I suppose (adjustable to your system’s preferred setting) eg. My equipments are 230v, but found them best sounding at rock steady 228v.

Hence ‘conditioners only’ don’t work for some. Other candidates I’d like to try are Stromtank, Torus etc.

I have an "all digital source" audio system and each time I've upgraded the power conditioner (Furman->PS Audio P10->PS Audio P15) I've found the performance of my DACs improves (tighter bass, improved stereo image and soundstage, better resolution) for both listening to disks and streaming from a Roon server.

A PS Audio regenerator is definitely something you simply must try in your own setup to determine if it's something for you.

Hearing results will depend on your homes power quality and how your setup responds to without and with one.

Some find it to be a waste of money, others like myself, actually "hear" overall improvement. 

No one here or the audio forums can give you solid advice on what's "best".

Wouldn’t installing a simple Greenwave filter solve a lot of the issues??

Was thinking about buying a Greenwave EMI meter which might be interesting.

If I can achieve a very very low reading than why bother getting a PS 15.

Also since the P 15 is being used to re-create an electrical signal why would there be a need to attach it to the wall with a very expensive power cable?
