Mr Speeed,

Keep us informed of how your combination works out. Many times we only hear when amps do not work with the M80's.

Also, Tariq has a good suggestion. If you also plan on the VP180 center channel you may want to consider the XPA-3 instead of the XPA-2. If you go with the VP160, you probably wouldn't need to worry as much since it is a much easier load to drive.
