Gryphon Antileon EVO employs true Class A bias for instantaneous availability of full current at all times.

Gryphon rejects any biasing scheme which attempts to simulate Class A bias by switching to a higher bias level when a more dynamic signal is detected. This type of sensor can only respond after the fact, because it is not possible to adjust bias rapidly enough to accurately “track” dynamic changes in real time in music which is rich in impulses.

For situations in which the full power of the Antileon EVO will not be required (a small room, undemanding music, background listening, efficient loudspeakers, etc.) the owner has the option of selecting full or reduced Class A bias via front panel controls.

For a more flexible approach, when paired with a Gryphon preamplifier via Gryphon’s proprietary Green Bias Link, power amplifier bias can be adjusted automatically in relation to the position of the preamplifier’s volume control. The user always has Class A power on tap as needed at any given time with massive power reserves ready and waiting.
