Is it just me or is "Metro Detroit" unnecessarily broad in comparison to Ann Arbor? In fact, doesn't Ann Arbor just about fit into Metro Detroit? Anyway, Ann Arbor or anyplace else on the Western outskirts of Metro Detroit would make sense to me. It's a lot more convenient when coming from outside the Metro Detroit area.
I'd offer my apartment as a meeting place, but it's too far away and definitely too small for more than 10 people or so. But having some high-end speakers (my Infinities) to compare with a bunch of headphones would be fun... I guess that's like good audio dealers though.
Count me in, anyway!
