I read most of this thread, and saw lots of complaints of BB not having Klipsch set up right, and this and that, so I thought I would give my experience/thoughts.
Someone previously made a good comment that any display in a retail store is difficult to maintain because you have Joe Customer coming in thinking he knows what audio should sound like messing with the settings, or some kid who thinks he's funny cranking it so that the store next door can hear it.
My local BB in Independence MO has a display with a nice HDTV, and I have sat there and killed time (waiting for dinner reservations) and I must say I think they have it sounding pretty good. I just wish BB, or some other store around me carried the reference line, and I'd probably go sit there more often.
Now I feel that I've said a lot of positive things about BB, so let me just say BB sucks. (personal opinion) I'm not some BB advocate, just have to give credit where credit is due.
