Mistico, welcome. Your 1400 can certainly drive the M80s to a very loud level. Despite the Emotiva comment, the M80s are in fact a quite easy load as speakers rated at 4ohms go(possibly a 6ohm rating would follow typical rating practice more closely). You'll find out whether the 1400 drives the M80s loud enough and long enough to fit your normal(almost any amplifier can be forced to shut down)use pattern. There's no good reason to assume that it won't be entirely satisfactory and go off looking for another amplifier at this time.

Enjoy the music, not the equipment.
