I agree with Rcprince. Lamm M1.2 is a fine amp. Back to Boulder, 2050( 1000w/ch mono ) is $71K/p new in US. Just to let you know. For me these are the best solid state amps availabile, maybe new Krell Evolution One will be an alternative? Stereo 2060 ( 2x600w $39K ) is also excellent choice. They will sound even better( to me ) with 2010 preamp. Some other guys have good results with tube pre like ARC REF3. 1000 series is almost as good, 1050/1010 combo is a lot cheaper, differences in sound are not that big.
