Your thoughts on best audiophile speakers in $10,000 neighborhood?

I recommend the Spendor D9.2.  Currently running the D7.2 and loving their sound.  The Spendor D series don't look super impressive at face value but they are the closest thing to a jack of all trades design I have heard and owned.  

Deep special bass impact and tone because of a well tuned long bottom firing flared port. 

An engaging, smooth and detailed midrange that is a trademark of the best British designs. 

Sweet detailed treble that is uncanny at times without being too much.  

Fast, efficient near horn like dynamics. Quick transients with great energy, perfect for following rapid fire rhythm and drum sections.  

It is suggested to avoid framing speakers solely based on a price tag. In publications like Stereophile, the price range for a loudspeaker can vary significantly even within the same class. Your price range may fall into the "restricted LF class A," "class B," to a "restricted LF class B," which you can use as a starting point for your search. Depending on your personal taste in sound traits, style and type of drivers, layout your basic requirements on speaker specifications such as efficiency, size of drivers/speakers, frequency responses, etc. Matching with your current gear is an imperative criterion as well. Most importantly, you need to audition them in person, ideally with in-home trials for at least a good number of hours, allowing the speakers to break in. I went through this hassle twice when selecting my main and secondary sets of speakers, and it is not an easy process that you can simply expect an answer from by throwing the question to Audiogoners.

@yesiam_a_pirate Dont you mean Audio Dimensions? I grew up in Birmingham and spent many hours there… bought a used ARC SP-3a1 from Harry - wish I still had it.  Was. Very sad when he retired last year due to health issues 

Find a reduced price on a pair of Monitor Audio Platinum 2003g speakers. 

I am also very much in the PureAudioProject camp. They deliver a very natural, open and pure sound.  Because they are open baffle, bass waves from the back of the speaker and the front wave interact and cancel bass, so they are a touch lean in the upper bass to deep bass (the cancellation grows progressively more severe as in goes down in frequency).  I am not a bass freak so it does not matter that much to me given how good they sound.  There are many options for the midrange/high frequency drivers--wooden horn, conventional drivers, coaxial drivers, Voxativ field coil wide range driver (the most expensive option).  

The Volti suggestion is also good--they make decent, affordable horn-based systems.  The integration of the bass driver with the horn is a bit off, but, that is, to me, a minor flaw given the positive attributes of the system.  You get the lively, vibrant sound of horns with only a hint of horn nasal colorations.  Something like a Klipsch Cornwall is another good horn choice, but, they can sound a bit ragged and peaky unless someone who knows what he is doing swaps out internal parts.  

If you can/must place speakers near the corner of the room, you should audition Audio Note speakers.  They are very musical, lively, yet relaxed (not edgy sounding) and one can listen to them for hours on end.  Among other conventional speakers, I like ProAc speakers--they too sound relaxed, but not sluggish, and are good in long listening sessions.

Good luck in your search.
