I have had a M80 in my main system now for about 15 yrs mated with a CX1000 the last few run to Klipsch Cornwall II's. Been a big fan of the Yamaha stuff since i first saw them in the mid-80's and didn't have the money then to buy them. I bet they are outstanding with the LaScalas.
You might want to try adding a tube preamp with either of these units if you want to experiment. It will open your eyes how wonderful the setup sounds with classic jazz or classical music. I ran this type setup with a M65 and Klipsch KLF20's and fell in love with the big soundstage and the ability to distinguish the individual instruments. Of course the mids with a tube pre are their big selling point. With the high efficiency of the LaScalas you should be able to run in class A all the time.
