Antileon Evo Stereo

Now, the Gryphon Antileon EVO, available in stereo and single-channel configurations, takes the next evolutionary step. A long time coming and well worth the wait.

CURRENT EVENTS

All amplifiers are not created equal, even if their published specifications might suggest otherwise. The extreme high current capability of the Gryphon Antileon EVO, for instance, is something that must be experienced first-hand, not merely gleaned from a specifications sheet. The wattage (W) that an amplifier is capable of generating is in fact the mathematical product of two factors, Voltage (V) multiplied by Current measured in Amperes (A).

On paper, a low-current, high-voltage amp would appear to produce the same number of Watts as a low-voltage, high current amp, but only if one does not take into account the crucial fact that the ability to generate high instantaneous current is far more critical and relevant to actual audible performance.

UNAPOLOGETICALLY UNCOMPROMISING

Recent decades have seen concerted efforts by audio manufacturers to encourage a shift away from high-power Class A amplification in favour of newer, more “efficient” topologies with claims that they can deliver the same level of performance in a lighter, more compact and decorator-friendly form factor.

The truth behind these specious allegations and the true motivation behind the promotion of lightweight amplification are very straightforward. It is an elementary exercise in cost cutting.

CLASS A BIAS

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.
