should i save my money and get the 818 and 7125 or are there any sonic benefits getting the 3009? i don't need sub eq and can't find any other receivers less than $1000 with audyssey xt32. i have never done this kind of setup before so i am asking you guys. i don't understand all the specs so where would my extra $400 be going if i got the 3009? since i don't need the onboard amps and the 818 seems to run cooler that seems to be wehre my money would be better spent. thanks in advance.
