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! :)

The Paradigms may be a great candidate for room correction/EQ. The speed and transparency of beryllium is pretty much unmatched short of diamond drivers. But the Persona series do veer a bit farther from neutral in the +/- FR variance based on the public reviews online. With some driver materials you have to worry about rising THD with EQ but its not an concern with a driver material as clean as be.
I’m 45 years old, and have spent the last 20-odd years searching for speaker Nirvana, and finally found it a couple of years ago when I got my first ever Harbeths. They exhibit just a beautifully, perfectly flat EQ from bottom to top, which means they are incredibly relaxing as no frequencies are harshened in any way.

I could only afford the smallest model at the time (P3ESR) which doesn’t go much lower than 75Hz, so a sub is essential. But with the addition of a sub I have * almost * all I want. The only time I find them lacking is with large scale orchestral classical music, due to their small size, but for everything else - rock, jazz, folk, etc, they are perfection. They reproduce acoustic instruments like piano, guitar and voice with extreme accuracy.

Oh, and a major factor for me was how good they sound at neighbour-friendly listening levels. You don’t have to blast them to make them "come to life."

With a bigger budget I would have gone for the M30.2, which will be my next upgrade, but I’m in no rush with the ones I have.

You should definitely check out the Harbeth 7es3.  They also sound amazing.  Great all around speaker and you probably don't need a sub.
