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

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.

Thank you Fripp1, if the Chang Lightspeed I'm going to test won't satisfy me I'll certainly consider your Dmitri.

I had a 20 amp equitech for a number of years and it was great..
I now have the 15 amp core power equi core 1800. It supplies plenty of power for all my components. Runs totally quiet and cool. Makes a huge difference in the noise floor. worth looking into for sure..
No hocus pocus. just uses CMR via balanced power.
