    I have had some time with the FA-22 amplifier and it has surpassed all my expectations. Very textured and present bass with vice grip like control, while still having smooth and extended highs. It pulls me into the music in a way my other very expensive amps do not. Imaging is my thing and I am transported to the venue and can see the performers in their places.

    The FA-22 is an involving, rewarding piece of equipment. The way the FA-22 conveys voices, instruments, the space between them, the overall acoustic is convincing! To follow individual musical strains and not to lose the perspective of the whole is so enjoyable with the FA-22. Well done, Flux Lab!!

    I’ve had a few days to enjoy the Flux amp, I’m very impressed. I can listen more deeply into the music, and admire how good some of these musicians really are! So enjoyable and effortless. Excellent price-to-pleasure ratio. Great job!
