Clark, or Oil Can,

I am powering my Martin Logans with an 85 watt per channel amp and it does a great job! I do have them bi-amped, but I have never noticed them stessed or strained when I turn them up.

The tube amps I have been looking at are only rated at 40 to 50 watts per channel and should have NO problem pushing the Martin Logan speakers.

Oh, and of course the Inside Sales/Customer Service guy would recommend all ML stuff. He is true to his company. What works best is to go out and listen and make your own descision.
