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

So Elizabeth your experience says the variations provided by an AC accessory (from cable to regenerator) are impredictable. A technically advanced component designed to improve AC may also slightly change the tonal balance and that could be welcome or unpleasant to my ear possibly at a higher level compared to the "base improvement" it will certainly give.

I really need to audition the P20 in my system before buying.

Thank you for your help!

Thanks for all your hints.

I thought the PowerPlant was much more an established certainty.

I'm now checking the Chang Lightspeed filters. Which model do you own Don?

Plus does Running Springs Audio have a website? Is it still on the market?

Thank you!

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!

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