Moving to a dynamic speaker from a Electrostatic

At your 15K price point I was very impressed with the Martin Django's. No, I don't own them, still using my Apogees, but for a cone speaker the Django's had all the slam you would expect (and generally miss in a planer) plus a transparency and soundstaging that didn't have me missing my Duetta Sig's much at all.

I made the move 2 weeks ago and went with NOLA KO's; I am still playing with positioning but like what I hear so far.

There really is no replacement for large electrostatics. What ever way you go it will be less than what you had. I can only suggest a smaller stat. The see through Martin Logans don't dominate the room like the Sound Labs do. At least not the smaller ones. That would be the direction I take.

Maybe the Summit X electrostatic hybrid speaker would be the perfect balance between realism and dynamics.
