as you guys know already i have the 7075 amp and my room dimensions are 15x25x10ft and the room opens up into a living 11x12x8ft and large staircase in the back. the 7075 does the job but its cranked up pretty high most the time (0.0 dec). if i was to upgrade my amp to a more powerful amp like the 7125 or the 7200 would i hear a noticable difference in sound quality given my room dimensions and current volume settings?

thanks for the feedback.

my speakers are: the Aperion 533-pt power towers with built in 8in amplified sub, 12 in powered aperion sub, 533 aperion vac center, and aperion in walls for surrounds.
