PS Audio PowerPlant P20 better than pure direct AC I get during the night?

gkg2k,

Running springs Dmitiri is no longer produced - you can get bargains for used item.  If you google you will see it is preference issue- some liked and others did not. 

That said, I have heard raves about Shunyata Tritonv3/Tyhon combo from audiophile I trust (he repaced Dmitiri, and P15).  A bit too expensive for my blood. 

IMHO get 2 of any of the brands mentioned, plug them and return one. You will not go wrong- ultimately it is system match and your subjective ears which will make the call.

Why not go with a balanced power output transformer.. This way you get common mode rejection, cool running power with no losses, very efficient. Most of all clean power you can hear. No gimmicks, proven for decades and used in most recording studios and pro audio..

I'm the OP and I can say I'm heading towards Chang Lighspeed.
I'll keep you posted.

Mikem : do you mean an isolation transformer? I know they're heavy and large. Could you suggest a model, please?

Thank you!

Gianluca,

I have a Running Springs Dmitri I would sell you if you are interested.  $2k plus shipping.

I have a P10 and found it was not good to run my amps thru it.  I use it for the digital components and by tweaking the settings it can be very beneficial.  I have a Denali 6000s for the analog components and it is wonderful but still the amps are better from the wall. If I was to choose one I would go with the Denali.  I recently added 3 dedicated lines for each of my amps and the other goes to the Denali and the P10 is off the Denali.  The dedicated lines were worth the cost.  Last week I added a PS Noise Harvester to each of the dedicated lines and WOW what an improvement.  I wish I would have tried them before all the changes to see if they would have made such a difference.  They are cheap I will say in my system the change was spooky good.  I am re auditioning all my favorite tracks.
