Find a vintage Philips CD-650, Marantz CD-52, or any player with the "CDM-4/19" swing-arm mechanism. These are bulletproof.
A functional, good-sounding CD player can be built by a hobbyist using a salvaged CD-ROM transport and an external DAC board. The critical success factor is correctly extracting the I2S signals from the drive's DSP. This project bridges digital and analog audio engineering, resulting in a personalized playback device that respects the Red Book standard. Future improvements could include a vacuum fluorescent display (VFD) and a dedicated clock re-clocking circuit for reduced jitter. cd player diy
