These are all good suggestions and I would add the Pathos twin Towers to this list(a Sam Tellig favorite). It is 35watts and has the most wonderful presence. I have owned several of the amps listed and this is my personal favorite in this price range. You can occasionally find one used in your price range.
Tube Amps for Coincident Super Eclipse
I have just purchased a pair of Coincident Super Eclipses, and am seeking advice from my noble HI-FI friends on which tube amp to mate with these speakers. I would like to keep my price below $3500. I auditioned them with the Cary 300SEI and that was pretty sweet. Any thoughts?? Thanks!!!
