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! :)

@gpgr4blu the Persona has both a beryllium tweeter and mid.  I would say accurate, detailed, revealing and at times forward.  I wouldn't say hard and bright at all.  They are well balanced.  Perhaps you like a more laid back, "musical" sound?  Like the Vandersteens.  That's a great sound as well, but different.  The downside of that to my ears is the lack of depth and detail.  It could be that digital music was the source which has a tendency to be hard and bright.  Did you listen to them with vinyl or a tube amp or pre?
Kii THREE.
Recent Stereophile review.
You don't need the amp, because the're powered speakers.
Highly recommended.
Just a general comment.  I think that some people who comment about Vandersteens lacking detail or sounding overly warm (i.e., to the point of being colored) perhaps have not heard the current line.  I find it hard to believe anyone thinking the carbon tweeter in the Treo CT models+ and the "reflection free" mid (let alone the carbon cone one) lacks detail.  It seems like an old stereotype that's hanging on.  Heck, I think even listening to my ca. 2016 3A Sigs would change your mind about that stereotype.  Consider yourself invited.  :)

Hi Vermeer,

Just to second what Audiotroy and Initm said, the Persona is a great speaker, but only if you pair it with the right separates.

As a case in point, I had an experience with a Delaware dealer recently who warned me over the phone, prior to my auditions, to stay away from the Personas because they were "too bright". However I took with me, to the audition, my Anthem AVM60 pre-amp- Anthem being the same company that manufactures the Persona Speaker. Upon hooking the equipment up, the dealer loved what he heard and apologized for "misleading" me earlier on - it turned out the Personas were bright on his separates, but not on mine. 

I auditioned the Persona 5F in Delaware, and prior to that the 3F at Audiotroy's store in New Jersey. Both speakers impressed me. Best wishes with you search! 
One side note, since Vandersteen was mentioned. The 2 model has been one of the best selling speakers for over three decades. Not many speaker brands can boast about that. When listening to speakers, often it is the design/engineer who is responsible for a great sounding speaker. Richard Vandersteen, Kevin Voecks, Jim Salk, Andrew Jones etc....
