Lamm 1.2 ref or tenor 175s

I have kharma midi exquisite speakers. I am considering an amp change. The two amps I am considering are the Lamm 1.2 ref mono blocks or the Tenor 175s stereo amp. Does anyone have experience with these 4 way Kharma speakers ( or any Kharma speakers) and either or both of these amps. I would appreciate your experiences with these amps and recommendations. Both supposedly go well with my speakers. Tenor has had past issues which I am told have been resolved. Also, Lamm apparently makes very nice amps. Does anyone have an opinion as to which matches up the best with the Kharma Midi Exquites?
