I'm running OSX on a Mac and that "system" has no noise that I can
detect thru the Senn 280's. I just mentioned this to verify that the
noise is not a defect in the headphones. My Linux box (the Dell) is a
separate machine. I tried your suggestion and lowered the volume
control on Amarok as low as possible (1-2%) and raising the master
volume on Kmix. I also tried it the other way around, and get about
the same amount of noise either way.

You mentioned the Sennheiser 280's require a "fair amount of output
to reach a decent level". Does this mean that headphones that require
less might not be as noisy? I'm wondering if there's some kind of
output spec that would give me better results.
