Audio Research and Martin Logan Montis

Jump on ARC asap would be great!!

The whole Audio Research Ref line of amps is about to be replaced with new SE versions this month. it should be easy to find a good deal on either amp right now.

Really? Dump a REF for REF SE with HUGE loss basically for a set of KT150s? Can't upgrade?

I rather dump, I meant jump on Magico asap would be greatER!!

I remember going to a demo that was showcasing top end Martin Logans with Bryston (solid state) vs the same Martin Logans with Jadis (tube) equipment. The Bryston gear was good no doubt, but the Jadis was magical.

I would be wary of any tube amp with these speakers to make them perform at their absolute best.
As at 4khz they give a nasty 3ohms and -55 degree phase angle. Which would be more like a 1-2ohm load as seen by the amp.

An amp that "almost" doubles it's wattage for each halving of load impedance down to 2ohm would be the amp to look for.
EG:
8ohms - 100watt
4ohms - 200watt
2ohms - 400watt

Shouldn't be a problem regardless of what the specs are. I drove my SL-3's with my VAC amp that puts out 32watts/channel.

Also, if you'll remember back when these speakers were current, Stereophile put together a recommended system with the ML Aerius powered by an ARC VT-50. The Aerius was a little easier to drive than the SL-3, but still, they weren't too far off. And the VT-50 had half the power of the 100.
