AMC Tube Amplifiers

Thanks for your input.
The amp I was looking at has the tube sockets installed so that won't be an issue. I have only heard their tube integrated amp a few years ago and it sounded pretty good- very rich. I am more concerned about heat and reliability. I would be doing this to switch from monoblocks to a stereo amp (inserted in a cabinet) and eliminate some clutter and wires from my floor. I have been trying to talk myself into getting a solid state amp, but just can't bring myself to do it. The AMC might be a good compromise.

Thanks everyone.
The price I would pay for the AMC is about 50% of retail for a brand new unit, which is what attracted my attention.
The Audio Refinement is nice sounding but does not have enough watts for my needs. I have also heard the 70 watt YBA amp drive my speakers and it sounds good, but not as rich as my tube amps.
Doug,
The electrocomp. is interesting but may not work with my speakers. I have heard that amp sound absolutely great, but it was with speakers that are much more revealing than mine. I borrowed one many years ago and it didn't work right with my stuff-no reflection on the amp. You certainly have it priced attractively. I will try and contact you by e-mail.

This is too rich for me; looks like I lost another good deal!
