The Master Power 3+ we have , drives a Wilson Audio Mezzo center and 2 Yvettes for the backs, and does a great job for a Sepultura live in Sao Paulo concert, but I can't say it was isolated enough to tune in on just the Dag 3+. The 2 Dag Progression monos drive the left and right fronts.
In another room the MC452 does indeed sound amazing with Wilson Audio Sabrinas for 2 channel.
You do have my curiousity peaked to just hear the 3+ for 2 channel.
