I'm with you on the Martin Logan 60's! If Best buy was my only option and the 60's were where my budget was, that would be the speakers in my house. However, while ML makes some great stuff, they have never been a great for value! (exception is I see used ML electrostats in like new or excellent condition popping up on Craigslist for $1200 to $2000 which might be worth considering if this is for one person - their sweet-spot is bigger than it used to be for good sound, but the true magic still only happens in one precise location exactly in the middle between the speakers). I am assuming that if this is for your living room, the "one seat" perfection is not applicable. You might still listen at BB and see how SQ drops when you leave that perfect spot!
I do think once your budget gets past the Infinity/JBL sale prices, the Canton ceramic is the way to go until you get to the budget of the Philharmonic BMR kit!
I have PreSonus R65's (which look kind of like the Emotiva speakers) with AMT tweeter and the ceramic tweeter is far better to my ear.
As far as telling you about the Chrono SL Ceramic speakers (have the form Chrono SL 5X6.2 - the variable value of X designates size and whether a center, tower, or book), what would you like to know?
I have the 526.2 (at my GF's), 536.2, and the 556.2.
How big is your space? and HT vs music? Type of music?
