Marantz CD50 working as a usual CD player, or working as a DAC connected to a Computer or a Streamer.
I've used an adapter board that is able to auto commute between the I2S signals. You can get it from this highly recommend seller:

For input interface, I chose a USB board with an SA9023 chip that supports 24/96KHz sampling rate.
I've picked the same track to show that the sound have no big differences between the CD format and the PC wave file - as you may notice.
The CD player can operate in Over Sampling or Non Oversampling mode. The additional I2S input is automatically selected when the CD player is in STOP or PAUSE - as shown in the video.
This modification is very convenient for having one CD player and one DAC in the same box.
As always, this is no more than a humble video just to demonstrate some jobs I've done for someone.
