High Efficiency Speakers Your top 3 or more

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!

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.

I had reminded myself to mention Daedalus in this thread and it slipped my mind. These are indeed excellent speakers, some of the best around, and they are indeed SET-compatible, but perhaps only higher-power SET.

I had an older pair of DA1s which I drove with a Viva Solista 845 SET as well as an ASR Emitter. The far greater power of the Emitter (and much lower damping factor) was really only evident at very high levels (much louder than I would normally listen).

Both combos were really, really, really good but I think I preferred the SET for that utterly pure midrange.

Lou says the current speakers are an easier load and thus even more friendly to no/low feedback tube amps.

Lou does really seem to like SS amps and I can only speculate that he likes music quite loud or prefers some other aspect(s) of transistor amps because they are very suitable for big SE transmitter triodes at least. I think a 300B would likely be marginal - despite the sensitivity I would think all those drivers draw some current.
