I hope i am not double posting. if so i am sorry. I was thinking about upgrading my reciever. I called a store near me for laughs and the guy says to get an amp instead. I have seen this talked about and it's a good idea. My question is what can i get in the $500 - $700 range or so. Also how many channels should i look for? i'm thinking 5 channels for all my speakers since i have no way to calibrate my sub with threciever i have now. I'm going up to see this guy tomorrow and i'd like to be sure i have some sort of idea what i'm talking about.
