If you love music and can't get enough of it, then this MP3-compatible 6-disc CD changer is made for you. You can change up to five CDs during playback without interrupting the currently playing track. Additionally, the DX-C390 offers the ability to program up to 40 tracks. The ONKYO DX-C390 incorporates the same innovative technologies found in ONKYO's high-end CD players: Vector Linear Shaping Circuitry (VLSC), Vector Quantizer Audio DAC technology (VQA), and Onkyo's exclusive jitter-eliminating "Accu-Pulse" quartz system. All of this ensures a sound quality that is unmatched in its class.
