Yamaha has a large selection of carousel-styled CD changers, so finding one to suit your needs is merely a matter of determining what features are important to you--they all sound and perform magnificently. The CDC-585 is in the middle of the line. The CDC-585 can change four discs while the fifth one plays, and play CD-R or CD-RW discs--an increasingly important feature since many people are burning their own compilations, and many smaller bands are releasing their music on recordable CDs that they can make themselves.
