I'm looking for a really good pair of monitors that feature optical input. Obviously they need to be self-powered and have a very good DAC (the big weak point on the Airport Express but it does have optical out which should pass along my ALAC files just fine). I've heard the Behringers and am not very impressed. I want something that really sounds good. Smallish near-field monitors desired. Roughly the size of B&W 685s. It's really a shame that the little B&W MM-1 speakers don't have optical in as they do contain a DAC.
