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! :)

- for a "classical" direct reflecting, beautiful speaker, no doubt about the XTZ Divine Alpha - as    good as BW800D3 - about the best speaker under 10k, and worth double - not efficient
- scale, transparence, dynamic, presence, in your face, room filling envelopping sound Tannoy Legacy Arden
- for an efficient, ultra transparent/accurate, ultra dynamic and ultra capable speaker, Tannoy GRF (new versions) - normal price is US23,000, but you can get them for less 15k -  If you get this, prepared to be shocked (coming from a guy using Westminster GR)
It is refreshing to read the Tannoy name appearing in these discussion pages. Worthwhile remembering is that Tannoy have been producing loudspeakers since 1926. They must know something about this stuff!

For those who care about such things, Tannoy is neither fashionable nor trendy, and most definitely unsexy! But have a listen anyway. Tannoy  have more or less global representation, and a dealer should be relatively easy to find. You may like what you hear.

If shopping vintage is your taste, one of the best values is the late '90s Tannoy Churchill. Produced in limited numbers, I have seen lightly used examples go for well under $10K.  A steal!

Lastly, (and this is really going back!) do some reading on IMF, a mid 70's company among the first to successfully bring the transmission line speaker to market. http://www.imf-electronics.com/Home
Pioneered by the late Irving 'Bud' Fried, IMF's boasted a flat frequency responce which was as linear as I have ever seen. 'Accuracy' was not only graphically represented but also accoustically.  And because of the TL design, the bass was clean and true down to the nether reaches (depending on the model size). Not as musical as Tannoy IMO, but a classic in its' own right. They are out there.

Good luck on your search.
@vermeer I went through a similar exercise earlier this year.  I spent a couple months listening to speakers at that price point.  My end choice came down to 3 speakers, the Persona 3F, Sopra 2 and Legacy Focus SE.  I took the Personas and Sopras home together for a side by side comparison.  They were the two most detailed/accurate/revealing speakers I had heard.  In the end I chose the Persona.  The Sopra by comparison was flat and laid back.  Both are very similar when compared to all others and it may have to do with the beryllium.

I chronicled my search here.

@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.

You don't need the amp, because the're powered speakers.
Highly recommended.
