Hi.. just ordered a B&K 30. Below is a link to a pretty thorough review. I would guess that if music is as important as DSP modes then the ref 30 should be near the top at its price point. Especially since it has 5.1 inputs and analog bypass on most of its other inputs. http://www.hometheaterhifi.com/volume_7_4/b&k-ref-30-preamp-processor-12-2000.html Also Dolby Pro logic will be comming soon, but that is not a good reason to wait since it and the discrete surround ex updates are implemented on a simple firmware chip that your dealer can install or even as user. Those formats are after all just algorithms embeded in code that the Motorala DSP decodes.
