@bdp24-We should absolutely get together if you come to Austin, have a meal, do some listening, go out and hear a band or two. I don't travel as much as I used to, but a little advance notice would be good.
One further thought that is indirectly related to the topic:
I realized at some point that my systems (particularly the main system where I've spent the most time and effort, leaving money aside) allows my brain/ear/gut to take in the music without as much "processing" to "fill in the gaps." Musicians are often able to get the gist listening to a boom box because their brains are wired for music. For audiophiles, whether or not you have music training, I think it is a little more passive being in listening mode and requires some degree of attention. In that process, I've found that a good system doesn't require so much imagination--the performance can be appreciated without as much "work." I've never formally studied psychoacoustics, but I'm sure there is some "science" relating to this.
