I haven't heard the 13A or 15A Expressions yet.
But I do know this about my Montis setup...... Went to 2 Stereo separated REL S3 subs right next to the Montis and tuned them to accommodate the speaker, not overwhealm it.
Have a Krell KSA-200S currently driving the Montis, and with the addition of the 2 RELs, full bodied sound that seems like it would cost four times as much to achieve.
I wouldn't buy too old a Martin Logan speaker.
They are very reliable recently and you can get some great deals on ones that aren't too old. I had A TUBE AMP for 5 years on a set of ML ESLs. Sweet sound, but nothing like Krell amp with my tube preamp combo.
