I used to have M60ti's and now have M80V2's, which I've notied some improvement overall in sound. Axiom, through constant research and development, makes changes (some major, some minor) to the crossovers, drivers, etc. I would say from ti's to V3's they have made a lot of changes, and I would suspect in a blind A/B test the listener should be able to tell in a positive way. All the drivers and crossover are different from the TI series. But, unless you did a blind test, I'm sure the TI's still sound great.
Can't help you on the binding post issue.
