I read the thread mod Naim CD-player with PMD-200 into stand alone DAC and found it fascinating. I never thought of the idea.
I just signed up and wanted to know have others on this forum done this with other standalone CD players to use their DAC and analog outputs?
Sure there are many low to high cost external DACs available and technology and chips have changes and come far but just this idea was pretty cool.
I would think a 24-bit DAC would still be better than say a old 1990s 16-18-bit DAC...for filters and oversampling, etc.

You can take out the DAC from the case and put in a different housing, or you can buy another DAC chip and build one yourself. The old DAC will be old electronics, and maybe less resolution.
You will not save much, most DAC are cheap.
Use a software based DAC, the CD players have wear issues, and are more or less obsolete.
Blank CD and DVD factories are mostly closed.
Now people use streaming for music, don't even store on device, storage is on net, cloud, whatever.

It is a subject that crops up in one form or another from time to time but rarely goes anywhere. BTW, the name for this kind of thing is Technology Insertion. Would be interesting to stick the new Rohm dac in a Sony CDP-101.
I'm actually undertaking a project to do this right now with my Pioneer PD-91 CD player. (the laser is dying and I want to give it a 'zombie life').
I am going to post a thread about it with my detailed plans, but I've been waiting to collate more information first.
Currently the idea is to use a DIR9001 SPDIF interface directly into the digital filer (YM3414).
I have questions, I have concerns, but I have faith that I can make it work 🙂
It's a project that's rather outside of my comfort zone, so I'm trying to inform myself as much as possible before making silly decisions. I luckily have the help of some fairly skilled friends that can help my physically implement the modifications, because I don't think I would trust myself with a soldering iron on the Pioneer.
I was planning to do this with a board salvaged from a dead Teac CD player. The digital filter and DAC chips were well documented, so it looked straightforward to generate the input signals from an S/PDIF receiver. I still have a couple of the Analog Devices asynchronous sample-rate converter receiver chips in my junk box, and a through-hole CS8412 (IIRC). However, time passes, and I picked up a Cambridge Audio Dacmagic for $20 at a yard sale. But there is that old Philips CD960 in storage... if the damp and silverfish have rendered it beyond hope as a working unit, maybe it could become a DAC.
