I have Lamm M2.2 and love it very much but there are a few things to consider. M2.2 is certainly considered a great high power amps but considering choices of speakers nowaday and Lamm's relatively low damping factor, it may or may not be the best amp for your speakers. I had a pair of Usher Be-20 and a few amps went through my room during that time. Older pair of Spectral DMA 160, Jadis JA200, Plinius SA 103, ASR Basis Exclusive II and then Lamm2.2 To my ears, Lamm has the best midrange, a little dark on top but well extended (more so with US Amperex pinched waist 6922 than pretty much every other 6922 tubes I tried, other tubes that I tried such as Mullard, Mazda, Gold Aero etc. Lamm bass is deep, tight but does not have the punch or control Usher's dual Eton drivers nearly as well in comparison to Spectral or ASR. Even Plinius SA 103 is a touch better in this regard. However, Lamm's lower damping factor seems to match my current speakers, Magico Q3 much better. Unfortunately I don't have a chance to hear Q3 with any other amps beside Soulution 710 (but in different room). I actually prefer Lamm as Soulution sounded incredibly clean and fast but does not sound natural to me. I kept thinking that no tympani and bass drum is that tight. I wonder if that might have something to do with Soulution extremely high damping factor (Lamm listed its damping factor as 82, Soulution >10,000 ). I would love to hear VAC but it is not available locally here.
