Best analytical loudspeakers for strings (midrange)?

Folks-

I am interested in comparing Wilson Yvettes (can obtain a discounted price, and which I have used in my house) versus Paradigm Persona 3F or 5F passive loudspeakers.

My system now combines McIntosh preamplifier, hybrid amplifier, PS Audio DirectStrem DAC, and transport, TIDAL server. My listening room is 300 square ft and has been optimized sound insulation (absorption and reflection tested using an audio engineer).

Although I love rock, electronica, jazz, and classical music, I want to be able to have high-resolution separation of different strings (violin, viola, cello, bass) in orchestral music, or even as solo instruments. I am a scientist, and I want to listen to high resolution ("clinical") sound.

Any advice? I have Wilson WattPuppy 7's and love the resolution, but I want to upgrade these speakers. I know that Vandersteen, Magico, etcetera are all great speakers as are many other brands, but I have limited my options at this point in time. 

Are the Paradigm Persona loudspeakers a better alternative to the Wilson Yvettes for string resolution?

Thanks in advance for any advice. - Gerry
