Comparing sound of Tenor 150 HPs vs. Lamm M1.2

After reviewing the archives, I could not find any specifics on the similarities and differences in the sonics of the Tenor 150 HPs hybrid amp vs. the Lamm M1.2 amp. I would be looking at using these with Kharma ceramique speakers. It seems that some favor one amp, while others favor the other. While I have extensively heard the Tenor, I have not had the ability to listen to the Lamm (and may not get the chance before I must make a decision). My question primarily relates to how the two compare with respect the midrange characteristics. Thanks.
