Since it is the beginning of the year, it is once again upgrade time! Whoopee! I have really gotten into MC SACD over the last six months, but I am also really interested in DVD-Audio. The problem is that I have a Sony SCD-555ES and Denon 1600, which I am going to keep for a while. I would like to upgrade my setup to a pre/pro or receiver that either has two 5.1 ins or has the ability to configure 2 ch inputs into 5.1 inputs. So far, I only know of the new Sony ES and Denon 5800 receivers to have two sets of 5.1 ins, and I only know of the Lexicon processors to be capable of assigning inputs to become 5.1 inputs. If anyone knows of any receivers or processors that have either of these capabilities I would greatly appreciate it. Also, the 5.1 inputs must be analog pass-through, not digitizing, so that the signal stays unencumbered throughout. I wouldn't mind if the signal digitizes and only sends out a bass signal, but I do not want the 5 main channels to be converted in any way. Thanks for all your help.
