Marantz CD4000 (2000)

The Marantz CD4000 is a single-disc CD player launched in March 2000, part of the company's Century Series. The Japanese-market documentation says it brought "high sound quality technology and high sound quality parts" to the lineup, including a digital servo and a bit-stream DAC. It played CD-RW discs, still a notable convenience in 2000. Outputs are a coaxial digital jack and the usual stereo RCA pair.

The feature set was practical for the era: edit and peak search functions, shuffle, program playback of up to 30 tracks, and fade-out/fade-in. A wireless remote was included. The front panel also has a headphone jack with its own volume control, which at least one long-term owner singled out as a favorite feature.

The record on this model is mixed. One Gumtree listing claims the CD4000 uses the Philips TDA1545 DAC chip and a Philips transport. Another credits the TDA1305T filter-DAC. The two listings may refer to slightly different regional variants, since the CD4000/N3B and CD4000/F3N suffixes appear on some units. Without a service manual confirming the chip, treat that spec as unverified. A 32-page service manual does exist and circulates among owners.

Owner reports are generally warm. One Russian seller, the second owner, noted the player "still serves faithfully" and "plays without glitches, changes tracks quickly" after maintenance in 2024. An AudioReview user gave it 4.2 out of 5. A diyAudio thread titled "Marantz CD-4000 broken" describes a loading motor that runs continuously, but that's a single report, not a known pattern.

Asking prices vary widely by market: roughly 8,500-14,400 ₽ on Russian classifieds, £55 ono in the UK, and one YouTube auction reference at 7000 (currency unspecified). The RC002CD remote is shared across many Marantz CD players of the period, so replacements are easy to find.
