First off let me say I know nothing about amps,except I am in the market for one if I will benefit from one..I replaced everything except speakers and added more of those.
I have a pioneer sc-63,I think it's 120 or125 watts,2 MK 200 watt subs,MK s-125 l/c/r,MK ss-150 for surround and have ordered MK s-150 for l/c/r and putting other speakers elsewhere.I am looking at the 7700 and any feedback or suggestions would be greatly appreciated.Sorry for the long post and thanks in advance for your comments.
