FWIW, I have owned the Lamm Ml-1's and now own the Tenor's. They are both outstanding amps....I prefer the Tenor and the purity of the OTL design. I have used both with Kharma 1's, Audio Physic Avanti III's and Speaker Art Proklaim II's.
To answer your direct question, I think the MA1's would be an excellent match with the Kharma.
