Life of a PS Audio PowerPlant??

The PowerPlant to which Tiofelon refers will overheat. That's the main issue with it; and with the P500, as well.

They tend to overheat even when not loaded with more watts than recommended, and the cooling circuit tend to fail. That's been my experience with two P500 units that I have owned. I traded-up to the PPP, and have had zero issues with it. The PPP is very quiet, and doesn't overheat.

Stevecham, just to clarify: Does the P300 have a fan?

Bombaywalla, you may be right about the P300. If so, thanks for correcting me. My experience has been with the P500, which sucks. And with the PPP, which is good.
