I currently have a Anthem MRX 500 which I use as a pre only with a Cinepro 3K6III amp. It sounds better than the Onkyo PR-SC5507 I had did but now I am considering a MRX 510, Marantz 8801 or the Yamaha. 60% music 40% movies on a 5.1 system (Source Technologies speakers and subs). Will the New ARC sound better than the Marantz Audyssey XT32 or Yamaha correction? Thoughts and I realize I am comparing a receiver (the Anthem MRX 510) to processors but as I said I do not use the Anthems power only the Cinepro amp and it is a beast!
