I've read a lot of threads here regarding CD players; SACD, HDCD, 2 channel vs multi-channel, DVD-A & Universal players and am confused. I upgraded my home theater with B&W DM603 S3's & matching center in a 7.1 configuration using a Denon AVR 2805, playing DVDs and CDs on a Denon 910 single disk player. I don't own any SACD's, HDCD's or DVD-A's. Budget is $500 for the source. Considering a demo Rotel RCD-1072 or NAD 521BEE. I could spend a bit more and get a Denon DVD 2910 to improve both DVD playback CD's, or wait a year for CD formats, etc to become more resolved. Goal is to hear the best possible music out of my new B&W's. Suggestions? Sorry for a long first thread from a novice.
