@twoleftears The P5 fans are very quiet. I am listening in a dedicated finished basement room with an extremely low noise floor. With all but my subwoofers running off of the P5 I am using 34% of its capability. I just paused Beethoven's Symphony #2 to listen for the fans. I couldn't hear it at all until my ears were at P5 level, 18" from the unit! It is a very quiet low frequency sound.
If memory serves, PS Audio borrowed the fan set up from Audio Research as their tube amps need fans and they admired the effectiveness of the fans on the circuitry while running so quietly.
I don't know if this helps, but I had a Premier Power Plant before trading it in on the P5. The P5 is several orders of magnitude more effective at producing clean output power ( .1% total harmonic distortion out) and it powers my whole system( I couldn't run my McCormack DNA-1 amp on the PPP without the regenerator shutting down).
There is loads of dynamic headroom. All music is more expressive dynamically through the P5.
