I saw your thread at AV123 but hadn't gotten around to it yet, then saw this one and chimed in here instead. MMC owners have been hard to find so far (possibly in part to the lack of an Emotiva forum).
MMC owners could be hard to find because it only recently started shipping. Since the MMC/DMC are identical except HDMI switching vs balanced outputs, and remote, comments about the DMC would follow for the MMC.
I also think that because of the close relationship between Dan and Mark, AV123 will be the forum for Emotiva users for the time being.
