I would vote for the M1.2 Ref. I have been very happy. I wouldn't say they're HOT ... warm, but you can certainly always touch the fins on the side and the top. They do help keep my room warm during the winter, but do need A/C in the summer to keep the room bearable on the third floor of our house. Of course, the Tenors were my second choice, specifically the hybrids. But, unfortunately the company's financial situation scared me towards Lamm.
Which Lamm should I add to the flock?
I have a Classe' 301 amp, an Audio Aero Capitale C.D player which I use as the pre, and Piega P10 speakers. The Classe' had lemoned on me again, to the shop for the last time. I heard Tenor 75wp with this same setup, and it was beautiful. I am leaning toward the Lamm's, but this is where my ignorance shows. The ML2's or the ML1.1's? This is a major purchase for me (hopefully the last for years to come with amps), someday to replace the p10's. Thanks for any help and suggestions.
