I have a pair of Thiel 7.2 which were driven by the MC402 for a long time. Recently I experiemented bridging the MC402 (closely following the user guide and using a set of jumper wires), and powering only one speaker. The difference was a noticeable jump in dynamics, bass, sound separation, and overall more fun to listen to. Because I only have one MC402, I don't know what it would be like having two of them bridged as monos, but I am sure they will be great with my Thiel 7.2.
