"What's The Best Value Speaker In $5k-$10k Range?"

Metalphoenix,the people love or dont like ML's at all, so depends on yor personal taste. I like some aspects of their sound, but never bought the pair because it seems they are quite a bit fussy to set up, need lots of space, big amp, panels last a limited time, and they sound diffrently depending of weather. All of this are experiences from a friend of mine, who has them, and loves them, despite all. We live near the sea, and there are climate changes, must add.

Audiowoman, another friend of mine has Avalon Ascedents,with new Ayre Ax-5 integrated, together with Ayre dac.Cables are Audioqust, top of the line. I am not sure if Ayre and Avalona are good combination, maybe he needs to put all Cardas cables in system. If I were looking speakers to hook with your amp, I would certainly try Sonus Faber models

Amphion-Krypton2
Atohm-GT3
Jamo-909
KEF-207/2
Marten-Django XL
Vandersteen-5A
$10k should be enough to get these speakers on the used market.

...and I've found that in each area of life or hobby, there are gems available that might not carry the most popular brand name - or be the latest fashion - but that do deliver the best performance for the money.

If, if, if, you can find them used, AudioKinesis (a bit less than your budget used), Daedalus, and Eficion might well end your search.

I am rephrasing your question to:
Given my room size & gear-esp amp, what is the smartest move up in speakers to give me world class performance, reveal the benefits of any other upgrades I make and provides "tremendous value?"
Revel Salon 1.for ~$5000. Well below your budget ceiling.
You now have money for some power conditioning and perhaps some better i/c's and speaker cables. These will also give you the best bang for the buck if you buy wisely. I am sure many will share some thought on those, myself included. Cheers!
