Heard both the Tenor/3.2 and Lamm ML2/3.2 as well as the the ML2's on the Kharma Exquisites. The ML2's are by far the best of the Lamm amps, and by a wide margin. I owned the Tenor/3.2 combo, which I preferred to the ML2/3.2 combo. Both are very good, the differences I heard as follows:
Tenors are more dynamic, extended in the highs, transparent and open and have a more realistic bass. Better attack of notes, and a "you area there" sense. I found the soundstage, width and particularly depth more reasistic with the Tenors. Overall I found the Tenors more lifelike, to the extent that the Lamms sound somewhat polite and anemic by comparison.
