High Efficiency Speakers Your top 3 or more

Over 10k is lots of cash for cheap fostex midrange even if fancy cones coated.

I am lucky enough to own Daedalus Ulysses and can confirm that they are the real deal. Excellent dynamics and frequency extension. Lou Hinkley is terrific to work with and extremely customer friendly. I am using a Einstein "Light In Dark" 80 wpc tube hybrid amp and never run out of headroom. I did try Art Audio SET amp which did run out of steam at modest listening levels. I know Thom Mackris of Galibier Design is extremely pleased pairing Atma-sphere M60's with his Ulysses.

Feel free to contact me if you have any questions...Good luck!

That was a combo I was considering when I was looking at the Ulysses. The match did not look to be ideal considering Atma-Sphere recommends 8 ohm, flat impedance loudspeakers (no dips below 6 ohms), and the Ulysses are 6 ohms nominal (I don't recall the minimum impedance spec).

Is Mackris using Speltz Zeroformers to double (or triple) the impedance?

Tvad, we are not so strict about the loading on the M-60. I've seen it work fine with speakers that dip to 4 ohms at crossover points, IMO its always something that you try and see how it works. But Thom has had his M-60s for well over a year and a half and seems to really like the combination, so it seems that they are a good match. He's pretty demanding.

As Ralph suggested in an earlier post for another speaker a GM70 based dehavilland could probably swing it too, but it appears anything less than the most powerful SET may not do the trick with those.
