$250 Belkin, or $1200....

I've got one set of outlets for my entire stereo system. I've got my power amp plugged into one and everything else has to go into something. Should I just buy a low cost power conditioner such as the Belkin PF60, or will I benefit much by spending $1000 more on the new PS Audio Quintessence? I had been using a Panamax 5100 and it seemed to work just fine but it has to go into the bedroom system and now I'm needing something else. I've got a fairly expensive system (Pass, Sim, Bluenote, Clearaudio). I just wonder what kind of benefits I'll get by going the extra step up in $$$.
