Gifford,
Frankly the best one that I've seen, I used to own -- the Golden Theater GTX-1. What a joy to work with, as there was plenty of space for all the connections.
Regards,
Andrew,
Oddly enough I recently sold my Ref 30. It's a good piece, but B&K is slow to upgrade -- still waiting on Motorola to deliver final versions of the DSPs that have DPL-2 and DTS-ES. That isn't B&Ks fault, but they (B&K) aren't particularly communicative.
Operationally it is sound...
