I use the Super Eclipses. What can I say, they sound like real music to me.
Surprisingly with the Cary switched into 80 watts the Coincidents will play quite loudly, with a lot of bass slam. No need for a sub here. I don't usually find that in tube gear, without going for the very expensive stuff that I can't afford. I think I prefer this to the 50 watt switch. Kevin Deal, my audio pusher, er dealer, believes this as well.
They image fairly well, though they are used in a relatively large, tough room. (Oddly shaped, the room presents a challenge to any speaker combination.)
I like the looks of the speakers, and the fact that they are fairly efficient, and present a very easy load to a tube amp really helps. These things are built like tanks, at over 90lbs each. Supposedly, these are efficient enough for flea powered amps to drive to very good levels.
There are a number of reviews of these, and their brothers, the Total Eclipses, in the magazines. I think the Totals were given a Golden Ear or something in the Dec. 2000/Jan 2001 Absolute Sound mag if you're interested in a professional view.
