I am contemplating purchasing the Oppo UDP-205 or the UDP-203 for BD and a stand alone CD player. I am also purchasing a Marantz SR-6011 with 7.1 analog inputs. Which I think bypasses the digital processing and lets the signal from the source to pass through unaltered. So my question, is for critical listening on 2 channel audio, what is the best way to go? RCA or digital?
