Best high-efficiency speaker under 10K

I'll give you few options. All of these high efficiency speakers I've lived with and has been highly satisfied.

1) Daedalus Ulysses: So musical. So rich and yet detailed. Very easy to make them sing. Good for every genre.

2) Daedalus Athena V.2: Same as Ulysses. But little bit more coherent but doesn't dig as deep as Ulysses. Extremely room friendly. The longest I've ever owned of any speaker.

3) Pure Audio Project Trio15 Voxativ: Highly customizable and tweakable. Bass is punchier and image is oh so bigger, more detailed than Daedalus. However, requires more careful placement and more effort to make it as musical as Daedalus but totally possible. Very high value. Good for all music.

4) Pure Audio Project Trio15 Horn1: Currently my reference speaker. Please check the review on Dagogo. Doug is spot on this speakers.

All of them are SET friendly and I play a lot of rock music using my First Watt J2 or Line Magnetic LM 508 SET amp.

Tekton Double Impacts are a 4 way 98db/4 Ohm load floor standing speaker.  I drive them with an 8wpc 300b SET, but many drive them with 2-3wpc 2a3 amplifiers to satisfying levels.  They compare to speakers much more expensive than their $3300 price, but if you want to spend more you can always step up to the Double Impact SE for $6500 or the flagship Ulfberht for $12K.  The reviews confirm what many owners already know which is that these speakers are giant killers and they present the most coherent top to bottom wall of sound you likely will only find in the best electrostatic or ribbon/planar speakers.  They are a 4-way design using a novel circular tweeter array that acts as the midrange with the center position tweeter producing the highs along with 2x ported midbass drivers and 2x ported 10" bass drivers. There's an Audiogon group that's very active with countless reviews by owners along with a world wide group on facebook. Just search on Tekton Double Impacts.   www.tektondesign.com  

Without a doubt top of line reflector from reference 3a...call tash owner ref 3a. Its the sound of raidho for one third price. 

@bache Sorry forgot to hit the notify button. Here is a link to Charney audio with current pricing.

I concur with rodge827. As a new Charney owner I am amazed! Give them a listen/purchase if you can.
