Overview

Although we as quality conscious consumers would prefer to live in a world where product development is always guided by incremental, evolutionary improvement, most often it is driven by sheer economics. This year's model is typically only a marginal variation on last year's, in yet another thinly veiled attempt to separate the consumer from more hard-earned cash on a regular, seasonal basis.

Among the few exceptions to this rule, Gryphon Audio Designs have never subscribed to the ritual of annual product roll-outs. On the contrary, you only hear from us when we have something truly new and original to say.

This is the simple explanation of why the Gryphon Antileon Signature (Stereo and Monoblock) Pure Class A reference power amplifiers introduced in 2000 remained available for nearly a decade and a half. Because cynical planned obsolescence is never part of the Gryphon design concept, the Antileon Signature, like every Gryphon model, was engineered and built to remain at the forefront of audio performance for many years until we were able to offer a significant step forward.

The Antileon Signature, like its predecessor, the original Antileon, was born a classic, establishing itself immediately in High End circles as one of the most acclaimed amplifiers of all time. Loyal devotees around the world praise its singular ability to maintain a firm grip on even the most demanding loudspeakers and reveal the innermost soul of any musical performance.

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.
