I was at that shop recently Psychicanimal, about a month or so ago.
I went to Ann Arbor as I heard they had good shops as well, what a disappointment! I went to listen to some amps, my short time at that shop was *somewhat* productive, I was able to listen to 3 amps, one after another in just a matter of a few minutes of each other, BUT, none of them sounded good because of their setup! I was able to determine a few things between them, but nothing critical. When the salesman found out I wasn't buying that day, he seemed to lose interest in me fast.
There is one nice shop there though, Paragon. Unfortunately for me, they lost power just prior to me getting there.
One other shop I was at wasn't to bad, but very small! (Far better than the shop you were at though, as far as for an audiophile.)
There is a shop not to far a drive from AA, in West Bloomfield, called Ensemble, it's geared more towards HT, but it's an awesome place to check out IMO.
