With its carousel for five CDs, the Yamaha CDC-600 CD changer is a versatile CD changer that not only plays standard CDs, but MP3 CDs as well. There's even a USB port that you can use to connect your MP3 player or iPod. Thanks to PlayXchange, you can change CDs while the current CD keeps playing, which is useful for parties. Other than the ease of multiple CDs, Yamaha also though of the sound quality when designing the CDC-600, which you notice in the high-quality digital/analog converter and the Pure Direct mode. The Yamaha CDC-600 is a good entry point for any HiFi system, especially when combined with Yamaha amplifiers and receivers such as the A-S500 and R-S500.
