Our take on the Marantz CD6004

It's all about the sound

Warning: listening to this player may become habit forming — its ability to reveal the hidden musical textures and subtle nuances on your favorite tracks may render you incapable of turning it off. The Marantz CD6004 CD player delivers audiophile-quality performance with standard audio CDs, burned CD-R and CD-RW discs, and even the tunes stored on your iPod®. You'll enjoy finely detailed sound alive with warmth and rhythmic energy, thanks to Marantz's precision craftsmanship and carefully selected parts.

Better sound from your iPod®, too

Marantz outfitted the CD6004 with a front-panel USB port — a feature rarely seen on CD players. This port lets you plug in an iPod®, iPhone®, or even a thumb drive that's loaded with tunes, and enjoy listening to them through your home audio system. Plus, this direct digital connection bypasses your player's built-for-earbuds circuitry, taking advantage of the CD6004's high-end digital-to-analog-converter for the best possible sound from your portable music library.

Trickle-down technology for top performance

The CD6004 borrows technology from Marantz's high-end disc players for out-of-this-world performance at a more down to earth price. Its precision disc transport, double-layered bottom chassis, and reinforced front panel resist vibrations that can adversely affect sound. A hefty power supply delivers plenty of clean current for lively, low-noise playback. And gold-plated outputs help maintain sound quality by ensuring the best signal transfer to your stereo system.

This is my last CD player period. The sound is clear with great depth tone out of this world. Marantz has knocked the ball out the park with this unit. This CD player will make your music sound like music. It's all that for real.

Disc Compatibility

Disc Compatibility: The Marantz CD6004 Single Disc CD Player can play CD, CD-Text, CD-R, and CD-RW discs. It supports both 12cm and 8cm discs.

CD-TEXT: The Marantz CD6004 supports CD-Text information such as artist name and track titles. The CDs used must also support CD-Text for this feature to work.

MP3/WMA/AAC Playback: The CD6004 supports MP3, WMA, and AAC audio files that have been recorded onto CD-R or CD-RW discs in ISO9660 mode 1/2 or Juliet/Romeo disc format. The Marantz CD player will recognize up to 512 total files and folders on a single disc. The unit will also display MP3/WMA tag data information.

Playable MP3/WMA/AAC Files
File Format Sampling Frequency Bit Rate Extension
MP3 32/44.1/48 kHz 32-320 kbps .mp3

AAC 32/44.1/48 kHz 8-320 kbps .m4a

Audio Features

Aluminum/Glass-Resin Front Panel: The CD6004 CD player's front panel is constructed from aluminum and glass-reinforced resin, which resists harmful resonances that can harm sonic quality. The panel is finished in a soft black tone, and features a graceful curvature that complements any home décor.

Double Layered Bottom Plate:  The CD6004 employs a double layered bottom plate to prevent unwanted resonance that could lead to distortion.

CS4398 High-Performance D/A Converter: The CD6004 uses a Super-Audio CD grade 192kHz/24-bit Cirrus Logic CS4398 D/A converter to provide exceptional sound quality. This high-performance D/A converter is capable of handling high definition audio data streams (DSD and 24-bit/192 kHz PCM signals).

CD Playback Technology: During CD play, the PCM signals recorded on the disc are oversampled to 128fs inside the D/A converter and then processed by a combination of the dynamic element matching (DEM) and multi-element switched capacitors to achieve playback characterized by a high linearity.

HDAM-SA2 (High Definition Amplifier Module): The CD6004 utilizes Marantz's Hyper Dynamic Amplifier Module, or HDAM, at critical analog circuit junctions to insure smooth and ultra-fast signal transfer from one stage to another. Marantz uses HDAMs instead of standard op-amps, to render a more dynamic sound with less susceptibility to radiated noise, heat, and vibration. The unit uses an HDAM-SA2 for high-speed and high-quality sound.

Current Buffer Design: A current buffer design eliminates interference from preamp input circuitry. In addition, audio outputs are laid out in symmetrical fashion, allowing for more dynamic, accurate, and detailed sound and pinpoint imaging.

Precision System Clock: The CD6004 employs a precision system clock to virtually eliminate any jitter for distortion-free music that sounds like the artist intended.

Audio EX Function: This function turns the player's display and digital output off in order to playback higher sound quality from the unit's analog audio output.  With those two potential noise sources eliminated, you'll be able to hear everything just as the artists intended.

Gold Plated Outputs: The CD player features gold plated outputs in order to offer the best connection for your system. The terminals are chassis-mounted so they can take the strain of audiophile interconnects.

  • Digital Outputs: Two digital outputs, one optical (Toslink) and one coaxial (RCA), are provided for sending signal to the digital input terminals of a receiver, outboard D/A converter, or CD recorder.
  • Analog Output: The CD player also features a stereo RCA output for analog connection.
  • Headphone Output: The unit has a front panel 1/4" headphone jack with level control. The high-grade headphone circuit incorporates a high-speed buffer amplifier to enable headphone listening of high quality sound reproduction.

USB/iPod Connectivity

USB Port: The CD player features a front-panel USB (type-A) port. The front panel port is designed for USB (MSC) devices or direct iPod/iPhone connection. The front panel USB port is compatible with FAT16/FAT32 file systems and will play MP3, WMA, AAC, and WAV files. The CD6004 can support 700 folders and 65,535 files per folder. The unit will also display MP3/WMA tag data information. The front-panel controls and supplied wireless remote will operate your USB device or iPod/iPhone.

Playable MP3/WMA/AAC/WAV Files
File Format Sampling Frequency Bit Rate Extension
MP3 32/44.1/48 kHz 32-320 kbps .mp3
WMA 44.1 kHz 48-192 kbps .wma
AAC 32/44.1/48 kHz 8-320 kbps .m4a
Linear PCM 32/44.1/48 kHz 16-bit .wav

iPod/iPhone Direct: You can connect your iPod or iPhone to the front-panel USB port using the USB/Dock cable supplied with your iPod (not included with this unit).  Sound quality is maximized by using the USB connection along with the CD6004's D/A converter. Playback can be controlled using the front panel or remote buttons, or the iPod/iPhone itself. You can browsed your iPod/iPhone's music library from the CD6004 by Album, Artist, Genre, Playlist, or Track. The CD6004 will also display song/artist information, as well as charge your iPod/iPhone. The unit is "Made for iPod/iPhone" compliant and supports the following iPod/iPhone model features (as of December 2011):

Convenience Features

Dimmable Display: You can adjust the CD player's display brightness from Bright, Dim, Dark, or Off.

As you are selecting tracks, the display will show the number of tracks in the program, and the total playing time of the programmed tracks. During program play, you can repeat the entire list of programmed tracks, or play them in random order.

QuickReplay: By a single-action operation, the "Quick Replay" function enables play to be moved back from the current play position to the time equivalent to the setting (range of 5 to 60 seconds) and play to be resumed. This function makes it possible to return to a part of the track that was just played so it can be heard again.

Timer Play: When this CD player is connected to a commercially available external audio timer (sold separately), the unit's power is switched on and media playback starts at the specified time.

Auto Standby: With Auto Standby On, you can automatically set this unit to standby mode after the CD player is in stop-mode (no operation) continuously for approximately 30 minutes.
