Hi, As stated earlier, I'm leaning towards the Onkyo 600 reciever for my new home theater. I plan to match it with the JBL NSP1 setup for now until I purchase a pair of JBL ND310II's for the mains and thus turn it into a 7.1 setup. My question is, is the Onkyo 600 powerful enough for this setup? Is there a receiver better suited for this task that has at least the same features as the Onkyo and maybe more i.e. auto-calibration would be great? : ) Am I making a good choice for the mains? Thanks!
