I recently took a dive back into Martin Logans as well having had a few pairs in the past. At the time I decided to do so I was running a pair of Tekton Moabs with Krell, Primaluna and Rotel amplification that I'd had for about 6 years when I got the "change/upgrade" bug, I opted for a pair of ML Montis speakers (used but in pristine condition).
I now know that was an enormous mistake. Although the ML's were nice, they did not have the soundstatge, realism, impact or depth of musical character that I had become used to with my Tektons. The ML's were also fairly fussy about setup as has been noted, though I did "dial" the in the best I could.
On the other hand, the Tektons are fast, accurate, truly full range, brilliant at reproduction and, quite frankly, the best spoeakers I've ever heard in my 40+ years of audio/music listening. And I've listened to many of the so called best ovet that time. And they're not nearly as fussy about setup.
Needless to say, I sold the ML's and am now pursuing either Tekton's Encores or Symphonys.I'll be in Utah at the Tekton's facility this week auditioning to make that choice.
