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.



Slight quibble. The above assumes we can then convey the bitstream to the
DAC with no unintended spurious effects. The most well-publicised version
of this is 'jitter' in various forms.


Yes, I thought the OP (Andy) was asking if there was a difference in using the
same transport in a damped and undamped mode, so I assume the same DAC was being
used. So, depending on how well the DAC handles jitter, there may or may not be
an audible difference even if the bitstream from the damped and undamped
transports differ slightly.



In principle this should not be a problem. In practice it probably is not a
problem for most systems/disc. But it *might* be a problem in some cases
where the player/disc/DAC arrangement is unusually poor for some reason.


or if the DAC doesn't handle jitter well ...
