http://www.avsforum.com/avs-vb/showthread.php?t=1060855 I wish i had found that thread before i clicked order on the 5003...i would have known what i was getting into. Not saying it's a bad reciever...it's just a bit more advanced than my knowledge of home theater.
I just recieved my sr5003 and haven't had a ton of time to mess with it, still redo-ing the basement a bit more.
It's more technical than my buddies onkyo 607, i'm sure with enough time i'll get it figured out and have some beautiful sound coming from it...but from a plug and play perspective, that onkyo is hard to beat.
