Let’s do it this way:
Take a Redbook Cd and rip it to your PC. Make sure it’s error free.
Now we can either play the file through USB or play the actual CD, which I assume can be perfectly played by the drive.
In both cases, the actual bits going over the I2S (or equivalent) lines to the DAC are exactly the same, no matter how they got there. The only difference may be the clock source, where one it probably a crystal feeding the Xmos, the other a crystal somewhere in the drive region.
