Amp for Coincident Super Eclipse

I have had Coincident Total Eclipse Speakers for many years now and have run
them with Atma-Sphere MA-1 OTL's primarily, yet have sampled countless
other amps for the experience of it and to evaluate the amps performance
mostly, not the usual audiophile disease of never finding satisfaction. I live in
a very fertile community of valve amp designers and builders that often enjoy
the Coincident speakers for their revealing portrayal of music and as an
evaluation tool. It would be true to say that these speakers will make very
satisfying music and perform flawlessly with much smaller amps than the
MA-1's, I have heard many times as little as three watts do a very impressive
job yet, with watts comes some authority especially in the lower ranges.
Admittedly, predisposed to valves, for my personal tastes it would be more
than a bit of a step down to drive these beauties with semi-conductor style
amps. My experience is that valves take them to a whole different place and
the matching is as close to a perfect marriage as it comes. Mr. Blume's
speakers truly do it all and will be well suited with a very wide range of
amplification. IMHO you should listen to as many different options as humanly
possible, not only will you enjoy the experience, but learn things that all our
opinions can't teach. Hopefully you have audiophiles in your local and could
have a few listening parties. Happy listening!

Very wise advice from R_f_Sayles. Absolutely, if you do have the opportunity to try a wide variety of amps - do so and make your own choice. As you can see, both of us having done so came to very different conclusions as far as which amp worked best for each of us (though we are using different speakers within Blum's line). For me, what is gained by going to a high-current, high powered SS amp (KWA150) caused me to give up a six year love-affair with my SET amps. But I'd completely agree that neither yields the same qualities and each will have it's own strengths and weaknesses. One thing that has consistently impressed me with these speakers has been their versatility to sound great with a very wide range of amplification. I could not agree more with sayles' advice though - try it all out yourself and see what works for you.

I concur with both Jax2 & R_f_sayles. While I too have not heard the Coincident Frankensteins in my system, my Total Eclipse certainly want more than SET power especially in the low end. Tubes are essential, but I would consider 25-30 watts a good starting point. Of course, the rest of the system and the room it's in makes all the difference.

FWIW a 'high current' amplifier will not benefit you with Coincidents in general, as they tend to have higher impedances, which favor tubes. I think the lowest impedance of any of the models is 8 ohms, and some are 14. So the 'high current' aspect of transistor amplifiers is never invoked.

IME its a good idea to have some power on any of the Coincidents. You may think you are doing well with 7 watts, but when you hear what a clean 60 watts can do you might re-think that.

Israel's speakers favor tube amps and especially those that are zero feedback.

Pay attention to Atmasphere's(Ralph's) reply.
