Amp for Martin logan CLS Originals

Hello,

I had the CLS2Z for about four years. Most of that time I drove them with an ARC VT130. I also tried the Pass Alpha 100 watt mono-block and thought that worked extremely well with the CLS2Z. One thing to remember regarding usage of tube amps, because of the difficult load they put on the partnering amp, they eat through output tubes real quick.

I find it funny (odd) that the bass is an area of performance that the CLS got criticized for by most people, and in a certain aspect of bass performance I believe rightly so, but at the same time, I always felt that the bass that was there was some of the most detailed, quickest, transparent bass I've yet to hear. I think that revealing nature of the CLS bass performance was the hardest thing for me to get past when moving on to other speakers.

best,
Tom

Up until now I have only considered solid state gear. Based on your feedback I might want to check out 100+ watt Audio Research tube. What do you guys think of the rogue M120 Mono blocks?

Great suggestions in terms of tubes, however on the solid state side anyone with good results/suggestions?

Ultimately I would prefer to go solid.

Hello Dfelkai,

I would look into either Pass or BAT if you're thinking solid-state. Good luck and enjoy the search.

best,
Tom

Dfelkai,

You may try Spectron amps too as highly recommended by a friend who uses them to drive Analysis Audio panels with effortless authority and neutrality.

I agree that tubes are ideal.

If you must use solid state a used Innersound amp or new Sanders Sound amp will work well. They are designed to work with electrostats.
