This is a no-brainer: VP100. Why? Because it won't look as funny sitting on top of your TV.

In all seriousness, though, I've got M22s and and a VP100 and they blend very well, sharing the exact same driver complement. The main difference between the two is the shape and the lack of port on the VP100.

Is there a particular reason you are considering the M2 vs. the VP100?
