I have Focal Sopra 3's, and have never heard them sounding 'bright' except in an untreated room with reflective walls.
In my 13'10" x 19' room, which has a wool rug on a wood floor over a concrete slab, absorbtion at sidewall reflection points plus 88 sq ft of bass traps, they sound very well balanced across the frequency range, coherent and detailed without ever being bright or harsh.
Driving them with a Linn LK280 (recapped) amplifier, Linn Kairn preamp, Bryston bda-2 DAC. Source is a Raspberry Pi 4 streamer running piCorePlayer, USB output to DAC.
