I run my Zero One Mercury CD/HD player, Supratek tube preamp, and two Gilmore Raptor 500WPC monoblock amps with a PPP with no problem whatsoever. The fan doesn't even come on. I tried the amps directly from the wall and it does not sound as good as through the PPP - apparently the much cleaner power (0.4% THD) trumps the dynamic restrictions, at least in my system.
