More, please. I'm curious to know more about that headphone amp you have, and why a buyer should look at something like that instead of just going with a stock Yamaha/Denon/Sony amp for all your needs.

I hear what you're saying about the hearing, as well, Jerk and Faceblaster. My hearing is totally shot (birth defect, I require hearing aids) and some high-end fidelity would be lost on me.

That said, I can hear the difference between, say, iPod stock earbuds and a low end set of Sennheisers (which I have used the few times I've worked in the television industry).
