Another dumb question

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

Mostly all good answers. Bryston makes great stuff. If the VOLUME DIAL POSITION really bothers you. You can find a nice Bryston preamp USED at a fair price.
Most people have budgets to adhere to so price can be an issue. By having amp/preamp by the same mfg. these things usually are considered in the design.
Just remember it's the music that matters. If you're happy with your gear and the way it sounds, who cares what others think. Everyone has an opinion but remember that with your system only yours counts....IMO....... RAMOND

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?
Here is what is hooked up to one 15 amp curcuit
DSP a-1
sat receiver
tv
fm tuner
dvd
cd
vcr
sharp front proj.
panamax

Rotel 1080
Rotel 991
power sub 250wpc
And no, the house is not on fire (I checked)
