Martin logan need a good HT mate

Meridian 558. I use it with my ML Requests/ Cinema /Rel Strata sub and Sonus Faber Concertina rears. It has plenty of power.

Check out the Innersound Electrostatics Amplifier. They are designed to drive electrostatics and its low Ohms. I've just got mine to drive ML Aerius i and they are awsome! Incredible sound and great bass! I strongly recommend you audition one before getting anything else. They have a 30-day trial period, so if you don't like it, just send it back.
