Great looking install.
I think the M2 will do well - definitely better than the VP150 based on my personal experience. I recently switched to an M2. However I do not have the M80's so can't comment 1st hand on M2 matching M80's. In my install the M2 does better matching my M22's than the 150 did however.
Besides, with the 30 day guarantee you really have nothing to lose to at least try it.
