Well, I must be suffering from poverty, as I could not in good conscience vote for any of the proposed system configs in your survey.
I think there may actually be a small market for this, though. I personally know folks who have dropped $30K+ (or more) at ListenUp, got the fancy kit and house-call for setup and calibration, the whole nine yards (only to end up with a system that sounds worse than my garage rig). So there are folks with more sense than money. Can you snag enough of them to make this endeavor profitable? High end audio is a shrinking, highly competitive niche market.
