I have a pair of 13A they are very good speakers, you can not compare them to box speakers the clarity the expanse is very good. You do need good power to run them and the better your system the better sound. But this is true for any good pair of speakers, so don't get scared by comments above.Go listen to them.
IS THE MARTIN LOGAN Renassance 15A worth the $10,000 higher cost than the Expression 13A
Thinking of buying a pair of Martin Logan's electrostatic speakers. I heard the 15A and loved the sound. They are $10,000 a pair more than the 13A. Is the difference worth it? Has anyone ever compared these 2 speakers?
