Volume is not a problem, in any way whatsoever, I can produce the
entire volume range from silence to more than too loud (without
distortion) at customary and normal settings . I don't have
schematics of the preamp, CD player(s) or the Creek headphone amp and
even if I did I wouldn't be able to interpret their significance to
the issue at hand.

....well you asked me....

Of course one can listen to a bunch of recordings
and then decide for yourself.

Now there's an idea.

My understanding is that the way this issue often comes up is that someone
says something like: I'm going to buy some HD580 phones, and someone else
says: Well if you do that, you're going to have to buy a good headphone
amp. I don't have any problem with the suggestion that there may be an
exposure to wanting a headphone amp for a number of technical and
non-technical reasons. But I do have a problem with stating it as a global
requirement.
