Best high-efficiency speaker under 10K


I have never played in the high-eff speaker / low-powered amp space, but I've read so many things that I would like to give it a try. I own an EAR 859 integrated amplifier, De Paravicini's interpretation of SET. It's pretty incredible, especially if you consider its price tag. I am now in the business of choosing the right speaker. I listen to a lot of jazz and vocals and opera. So, I can do without the sub-40HZ frequency range. I would like to stay between $3K to $7K, certainly below $10K. Here are the options i am considering:

1) Zu Audio Essence.
2) Beauhorn Virtuoso (single driver)
3) KCS louspeakers (the model that uses the SEAS exotic driver)
4) Devore Gibbons 8
5) Living voice Avatar

If I had to choose right now, I'd go with the Beauhorn, but I know their limitations.

Any thoughts/personal experiences with the above or any other speakers in this range? Thanks.

Ggavetti, I can understand where you are coming from, but for me personally a speaker is a speaker and they ain't pretty,lol. I would go for sound quality everytime rather than the look of a speaker, or its resale value on the used market, I mean you could very well end up with something not as good as a speaker made with a personal touch just because it holds a better 2nd hand value than a non mass produced piece of kit?! If on the other hand you bought a 2nd hand pair for the price of a bag of chips you could/should be able to recoup what you paid if you decided they were not for you in the end. No loss. Result.
Then again there is always a plethora of reasonably priced lovely sounding gear on here, either way buying wisely should mean a lossless investment.
Let us know what route you decide to go.
You can never go wrong with Coincident Technologies. The Gallo 3.5 Reference at $6K is also excellent. The new Vaughn Cabernet at $8500 may be the best speaker south of $10K--heck, might be the best up to $15K.

Ggavetti,

I think it would be important if you first stated what YOU consider "high efficiency" to be.

Is it 92dB and up with a high stable impedance curve?
Is it 95dB and up?
Is it 100db and up?
I just received a pair of Beauhorn Virtuoso cabs and installed "new" DX4's. I am using Tempo Electric's single solid-core pure silver speaker wire, also "new". The Beauhorns are rated @ 106 and were purchased for, and soon to be, used with SET 45's, but currently powered by Heathkit SA3 (3) watts per channel. In a temporary small apartment setting, I've had volume set to 1/3 max. While not yet broken in, I am enjoying the heck out of these!! I am invited to listen to Musical Affairs Grand Crescendo's...w/12" PHY coaxial's, @97 rating? A very interesting theory behind thier cabinet design. They are above your $$ limit as new, tho. I second the suggestion of speaking with JohnK.

I also think these are interesting speakers. Please come back and share your thoughts with us.
