Searching for the most "accurate" speaker (below 15K)


I’m looking for the most accurate and resolving speakers (budget is <= 15K). Paradigm Persona 3F, Kef Reference 3 or Focal Sopra 2 are some of the options I can think of. Any opinions on how these compare? Should I had other options to this shortlist? The amplifier is the (absolutely extraordinary) Nagra Classic AMP.

Thanks! :)

Thank you all! I live in Portugal and brands like Joseph, DeVore or Decware are not available around.

Regarding the GoldenEar Reference, it happens that I own the Triton One and I do respect the brand a lot. But the fact is that, as I've improved the electronics their limitations became evident. Also I need a speakers who interacts less with my smallish room (and the GoldenEars do interact a lot)
Oran, I will check the ATCs ... regarding their active designs, do you have any opinion? 

Cheers
I’m a fan of Focal. Currently own Diva Utopia Be and had auditioned Supra 2. I’d go for Supra 2 if I were buying. The speakers on your list are all very good speakers. I think the choice will end up with your personal preference.

Happy listening!

This is a very fair statement on your part @vermeer 

I'm curious if you would/could share what exactly you felt the limitations were as you improved electronics.
