YBA Passion 650 never hides its origins. It’s a music lover’s amplifier that clearly translates Yves-Bernard André’s vision and passion. The 650 has more than enough potency in its design to translate music with power, dynamics, natural transparency and most important, correct timbre and musical imprint. Passion needs no second guesses. Seamless integration of technology in the service of music is evident even after those first few musical notes.
