Welcome!

I'm thinking the Yamaha may do OK, as it's 95 WPC and many owners here have Yamahas. IIRC, Yamaha is on the good list with Denon, Outlaw, H/K as far as receivers that can power the M80s.

It is nice to have that amp as a back-up, and it couldn't hurt to run them through it, but it may not be necessary.

I expect others with more personal experience to chime in shortly.

Let us know how you like the speakers! We love reviews.
