Power regeneration - good idea? PS audio?

A lot of people like balanced power conditioners.  Underwood HiFi sells Core Power Technologies that seem very good and worth checking out.  Best of luck. 

"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?"

Definitely any "audio mystery" as to why we PP users  get the fancy cable to power it. I have all Nordost from the wall. The MSRP for the PC is nearly half the retail of my PPP! 

Reality at least to my ears-  aftermarket PC into the PP doesn't "improve" sonics.If it does, it is so subtle if anything. 

Even the PS Audio videos don't have a concrete answer as to why you should consider one- you just do it. 

Part of the audiophool protocol.

Well this is all profoundly sad.

Unfortunately there appears to be no good rationale for spending $7500 for a P 15. Was really hoping it might help my home theater sound since the processors being made these days are of poor quality sonically.

Additionally to improve the flow of electricity via a regenerator to a quality amplifier in periods where there is a huge swing in electricity needs is ridiculous. Amps maintain Storage reserves just for this purpose.

I believe a conditioner has merit for use with a TV set where circuitry may benefit by hopefully softening a harsh electrical signal.

PP's are something to put on the list after you're convinced you did all the baseline essentials to dialing in SQ.

Dedicated line/decent receptacle before considering all the other madness.

Your alternative choice is "power conditioning" or whatever you want to call it, is another polarizing subject.

Audioquest Niagra and the like has their devotees.

Oh I am also still using my 17yo PSA PPP (out of regular ac line) in bed room to plug my big Sony Oled plus Marshall blutooth speaker into—even my 10yo nephew could appreciate the picture and sound quality improvements. My old P10 fared even better there but couldn’t fit into the cabinet.
