Power regeneration - good idea? PS audio?

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?

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.
