Ok guys I am looking for some straight forward answer wt opinion. I am looking to purchase a new av unit. i am running a yamaha v1900 with polk audio rti a9, rti a6 and polk surrounds. I really really wanted the pioneer sc-37 it posted the best overall performance in 7.1 for an av unit. holding watts per channel ect... the newer pioneer units seem to have lost some power when doing multiple channels. the sc-68 at 7.1 seems to drop to 100 x 7 rms power when its rated at 140 x 7 in reviews. The onkyo tx-nr5010 huge beast of equipment 145 x 9 can't find any reviews, i am assuming very close to tx-nr5009. They both give the option later to add an emotiva amp. they both come with room correction so which one would be the best?
