Abstrakt7 is right. MLs need a lot of trials-errors to sound right and in the first impression they do not seem to work with any components/cables. But beyond an acoustic and component settlement problems, the best bet is a good quality tube amp. It'll be much easier to set them up with VTL MB125 "big balls" tube mono amps or you should go for some 250 W/ch SS monster to be able to drive them(seriously the're "too heavy" for SS in general and most successful setups I'vseen with MLs are with tube power-amplifier(s)). In this case tubes will be much cheaper sweeter and reasonable.
Happy Listening!
