Hello Zak,
I'd agree with JohnK's recommendation. You'll likely find the Axiom M2's to be quite a lot more neutral than the Yamaha speakers.
Just be very careful not to push the tiny Yamaha amplifier into distortion. The Yamaha amp is rated at very high distortion (10%) and at a single frequency, 1 kHz (those are typical of mini-system specs, which enables the manufacturer to claim higher power output for marketing purposes).
Note that a small amplifier like this one pushed into distortion (clipping) can risk damage to the woofers and tweeters of the M2.
Regards,
Alan
