This is something I'd like to know too. I own the MA2275 and it is great, with a smooth and controlled bass and good separation. A joy to listen to and a very "complete" integrated amp, user friendly, riaa, bass/treble adjustments, many inputs and outputs etc. I have heard the Jadis Orchestra Reference and it is very different from the Mac sound. It focuses much more on the midrange but lacks bass control. That is why I'm wondering about the Jadis DA60.
