As a general question, who knows? But the question was very specific. This question should be answered by experienced Martin Logan owners. I would also contact Martin Logan for their opinion on the subject. Did they install two terminals because they thought it sounded better or just to keep up with the Joneses? In the end though, trial and error would probably give the best answer.
Bi-wire: is it worth it?
I am about to buy a sweet set of used martin logan stats. They have four terminals, and can be bi-wired. Someone has suggested I should bi-wire them. However, this would come at an additional cost, as I would have to buy new speaker cables. Does bi-wiring make a noticeable difference?
