Another dumb question

I was pleased with the improvement in quality I had noticed after adding a Bryston 4bst to my mains previously driven by the Yamaha DSP-a1's internal amps. The only drawback is that 4b seemed to require a higher volume setting on the Pre for the same spl as the DSP-a1.Then I borrowed a friends 4bst and bridged them for 800 watts per channel and the volume was less yet! This doesn't make sense. 800 vs 300 vs 110 watts? Hookups are rca and unbalanced was selected at amps. into Definitive tech bp10s. any help appreciated.

Thanks for the response. Is there an easy (read inexpensive) way to boost output voltage? A processor between the pre and amp for example?

What effect would line voltage or amperage have on my situation? Since my system has been growing,I have been planning to run a dedicated 20 amp curcuit just for my amps. Almost everything is in an entertainment center and running through a single surge/ line cond.in wall receptacle of 15 amp curcuit. I've never had any problems or tripped breakers but this has got to be pushing the limit. the leds on the panamax appear to be fairly accurate as they always show when voltage is low at peak demand times (neighborhood). They do fluctuate durring high vol use, but never near danger zone.I've heard mention of folks seeing a marked improvement after switching to an upgrade power cord, so is it possible that the draw from so much at once is partly to blame?
