I have not heard the ML amps with the Thiels. I have owned and auditioned several amps(Pass X600, X350.5, Ayre V-1XE, MXR, V-5XE, Mcintosh 1201s, 402, JC-1 monos)with various models of Thiels. And for me, as nice as they have been, none has worked as well as the FPB amps I own now with my Thiels. Good Luck.
