You are using a cdrom drive and an external DAC?

How about a little experiment:

Fit it into a PC.
Copy an audio track as a .wav file with and without damping,
then repeat with your stereo system playing some heavy metal
turned up to 11.

Alternatively connect the digital output to a soundcard with
digital input.

I would be interested to find whether there was a bit of difference
between the files.
