Years ago I compared my Oppo 95 against a new then McIntosh MCD500. Since it was easy to do, I brought the 95 to the dealers showroom and made the comparison. I thought the MCD500 was so much better that I left the showroom with a new MCD500. I believe the MCD600 would be even better. I now have an Oppo 103, 105D and 205 but these are only used for movies and video. Just to throw in some confusion, I did sell the MCD500 for a Esoteric K-03 and then to a K-01x which I preferred even more.
I also have a C1100 but with MC2301 mono's. I believe once you upgrade you CD player you will have a fantastic system.
