Why you will love it
PlayXchange
Yamaha says PlayXchange lets you change CDs while the disc that is playing keeps going, so the music is not interrupted.
The full-opening disc tray lets you change all five discs at the same time.

Pure Direct
Pure Direct is the same feature found on many Yamaha amplifiers and receivers. Pressing the button on the front panel or the remote shuts down the digital audio output and turns off the display.
Yamaha says this gives the lowest possible noise interference, and so the highest sound quality from the analogue output.
USB playback and sound quality
The front USB port plays MP3, WMA, AAC, WAV and FLAC files from a USB memory device. WAV and FLAC are supported up to 96 kHz / 24-bit.
Yamaha says the sophisticated internal layout of the CD-C603 has been further upgraded for sound with dynamics and clarity.
