I would expect the Paradigm References to match up nicely with the 990 and 7700 (the 770's replacement, apparently due to begin shipping in the next three or four weeks). I've got the previous generation Paradigm Studio's (60v2, CCv2, and a couple ADPv2's) along with a pair of Axiom M3ti's paired with a 990 and a combination of Model 750 and a pair of Model 200's. It's worked out very nicely for me.
