I need to replace my Yamaha CD player, CDC 585. I would like a five disk changer, and am thinking I should get a player/recorder ($300-$500 range). Am I trading sound quality to get the recording function? I'm contemplating the Sony RCDW500C or maybe a model with a hard drive. I have a DRA-685 Denon Amp and small Polk Audio Speakers (about three years old). Any help is extremely appreciated. Thanks!
