Cvman, I auditioned the Ayre Mx-R monoblocks and found them ok, but somewhat "dry" to my ear's. If you go to past threads on this subject you will get more information and polite disagreements regarding the sonic virtues of the Ayre's.
So, out of this two amps I like the Lamm M2.2 better then the MX-R's, they for me were more musical and real sounding then the Ayre's.
