Exactly! Just rip files from that transport in the four sensible
conditions - music on and off, large 'damping' mass attached and not
attached. Check to see if the files differ. If they do, investigate.
If they don't, forget it.

No no no SP! Try it my way, in a measured manner. Or, is the
'data-on-the-disk' the *only* thing that matters in this context?

Sure it is - what else would possibly matter in a device which outputs
a digital datastream? That's what makes this such an easy thing to
verify!

If it is,
you've run out of avenues and reached the sides of your box.

It's a box which has been well defined for twenty years - as has
auditory hallucination and expectation effects, which Andy *should*
know about, but is conveniently ignoring. Shrink, shrink thyself!
Also, Andy is reporting audio-related effects from a device which
outputs a coded datastream which is not in any direct way related to
the final audio signal.

No problem with
that. Just say, sorry Andy, I don't know.

(Having said this, the data might be different!)

Indeed it might, but this would indicate a seriously underperforming
transport.

Rob, getting the 'data off the disk' in a reliable manner is the only thing that
matters in this context. If the output stream of 1s and 0s from an undamped and
damped transport is exactly the same, then the damping doesn't make a difference.

Quite so, also if it is not affected by acoustic feedback from loud
music playing. Heck, put the damn thing right in front of the speakers
if you like!
