^^ Not sure, but I pinged Saturday Audio Exchange, which is local for me, and they have their M22 (two channel version of the M27) set up in one of their rooms, and got a demo version of the M27 in a few days ago. I'm going to swing by there with some demo material either tomorrow night or Saturday. Does anybody have any specific questions I should look into beyond the "when will it be available" kind?
