I consider myself an audiophile with pretty decent equipment, and I couldn't tell the difference between any of the high bitrates when I hooked my empeg to my system.

Of course, maybe I didn't setup the greatest test cases. I thought about going back and ripping a short little snippet at different bitrates. Anybody have a suggestion on a good piece of music to test with?

Although, since most of my listening will be done on my not so "audiophile" car stereo system, the point is somewhat moot.
