I Just bought a pair of LAMM M1.2 Reference monoblocks which have replaced my ARC Ref 210 monoblocks. The LAMMs leave the audio research amps for dead. I have also heard the Ref 5 SE / Ref 250 combo and again the LAMMs are clear winners. I have never heard an amp which sounds so realistic. I will be keeping these amps for a long time ( or until the next stroke of genius from Vladimir Lamm).
