Not only working as a standard CD player with incredible sound reproduction, but also the CD6006 is capable of playing back recorded CD's with CD tracks or MP3 tracks. Marantz have added very rigid feet to eliminate vibration delivering the best possible sound to your amplifier. For those times you are listening to MP3's or content through the USB (Universal Serial Bus) connection there is an integrated Digital to Analogue converter (DAC) which is a reference class CS4398 chip for optimum sound. There are many ways to connect the CD6006 to your Hi-Fi system, either with analogue phono cables or alternatively with either an optical or coaxial cable for a digital connection.
