I, too, was thinking about this for source components.

I really have to compare directly this P20 with the Torus AVR 60 BAL I have been planning on.

I use Torus RM15 Plus's...one each for my power amps. Regeneration is not the way to go for power hungry amps. Nothing beats the instantaneous hi current of toroidal transformers...versus amps plugged direct into wall outlet.

Without hearing it for myself I have never been able to get comfortable plugging high current power amps into any device, even an isolation transformer. (I am not in any way suggesting you and Mike are incorrect; only that I did not have a way of actually proving to myself the efficacy of power amps on an isolation transformer.) That is why I decided to forgo the system-wide wall mount Torus unit. It would solve any grounding issue, I know.

I decided to plug the four amps directly into the wall outlets. For the source components I want to use the Torus or, maybe, the P20.

Christian, since you have both the P5 and the RM15 have you ever compared them directly with your phono preamp?

you have more instantaneous current with an isolation tranny vs plugged directly in the wall (unless outlets come from a wall mount tranny). Huge difference in performance. My amps gasped for air direct into the wall compared to now with a tranny.

Absolutely; when i used to use a P10, amps (200+watt CF mono's) had to go from wall outlet, which was a 10mm spur. Now using transformers and cleaner, more transparent effortless sound. Regen is in my experience, not the best option, for source or power amps. A 2kva transformer will give nearly 9 amps, which is plenty, even for big valve mono's.

Hello,
unfortunately there are not many users of the PS Audio P20 directstream power plant out there, at least I don’t really read much about it?
Wouldn’t you recommend ist?

I had a P10 power plant for about one year in my system. First I thought it would be very good, but after some listening test I found it showed more space, more attack and precise bass, but the flow and naturalness of the system was less.
After that I have sold it, wanted to try a P20, but I have never done it yet.

What are your findings?
