Martin logan need a good HT mate

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.

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