I also had Marantz CD-67se. Not one but two that I purchased 25 years ago from a sale as far as I could recall. The SQ out of CD-67se is good but nothing special really to write home about. Both of them quit a while ago. I replace one of them with the vintage Rotel RCD 855 with the well-known Philips TDA 1541 chip. It performs brilliantly with detailed treble, warm midrange and solid bass, better than Marantz.
Comparing external DAC to CD player DAC
I have been using a well-known, inexpensive ($300), and well regarded DAC with an old MAC as a music server. I also stream TIDAL masters and use the CD transport through the server, all going through the external DAC. I recently pulled out my old CD player, a Marantz CD-67se: an "oldie but a goodie". The CD player with its onboard, 20+year old DAC is far superior to what I am experiencing with the external DAC, from any source.. Is this expected. I am not opposed to purchasing a new external DAC, but i really don't want to spend thousands of dollars to reproduce sound I can get from a 20 year old CD player. What am i missing? Could I be I doing something wrong, or could my external DAC be malfunctioning.
