Gryphon Audio Designs remains committed to discrete circuitry and Class A bias in the Gryphon Colosseum Solo power amplifier. As a result each monoblock weighs in at a hefty 80 kg.
True Class A operation has always been a Gryphon benchmark, because there is no substitute for the sheer musical magic of pure Class A. The Colosseum Solo operates in true Class A mode with maximum power instantaneously available at all times, for unrivalled speed, control and accuracy. Once you experience the effortless realism and musicality of pure Class A, there is no turning back.
Because 180 Watts of pure Class A power is overkill for the vast majority of applications (in particular with efficient loudspeakers, in small rooms, or at low listening levels), the Gryphon Colosseum Solo incorporates proprietary Green Bias circuitry which automatically adjusts bias level to match the selected volume setting when paired with a Gryphon Mirage or Sonata Allegro preamplifier. Tracking bias in this way significantly reduces power consumption and heat generated by the amplifier without compromising Class A audio performance.
For use with a preamplifier without Green Bias, the Gryphon Colosseum Solo features three-step (High, Mid, Low) manual bias adjustment.
