The CD5004 offers a lot of technology and features for $ 349.99. It incorporates " SACD-quality" Cirrus Logic CS4392 D/ A converters, which Marantz claims are very linear, producing none of the distortion caused by errors in resistor matching, no performance drift over time or with temperature, and low jitter. The signal paths for the two channels are symmetrical, which Marantz claims should improve the specificity of stereo imaging. Marantz' s proprietary Hyper Dynamic Amplifier Modules, used for the analog circuitry, have been trickled down from their Reference Series components, for which the HDAMs were developed. The company claims that these outperform conventional op-amps in speed and low levels of noise. The front panel' s aluminum central section electrically shields the circuits inside and the parts of the front panel made of rigid, glass-reinforced resin resist impact and help isolate the CD5004 from vibrations and heat.

The CD5004 plays CDs, CD-Rs, CD-RWs, and discs containing MP3 and WMA files. With the latter, it will display the file metadata, to help identify the disc and its contents. Also included is a buffered headphone amplifier and jack, variable pitch control ( designed for musician play-along) , a Q Replay button on the remote control that repeats the last 10 seconds played of the current track, and an IR Flasher input to provide connectivity to other components. Coaxial and optical digital outputs are provided.
