I've taken the M9 along on my daily route to and from work paired with the BGVP DM6 and it's a match made in heaven. I'm holding back on sound impressions right now as I'm still burning in both items. The M9 gets warm to the touch after using the balanced connection for a few hours. UI is snappy and quite fluid. A few translation errors here and there, but nothing what a few updates could not fix.
