Hello chaps, I'm looking at buying a dedicated cd player to couple with my Yamaha 1067 AVR. Currently I am looking at the Marantz brand and interested at the 5004 & 6004. My question is the 6004 worth the extra money for the quality? The 5004 looks a damn fine player, but I'm not sure whether I need to go the extra distance at the moment. Cheers in advance.
