Gryphon Apex: The Pinnacle of Performance
It has always been Gryphon’s mission to achieve the highest possible audio performance. in terms of sheer musicality, transparency and realism. With the Gryphon Apex Mono and Apex Stereo Power Amplifiers, Gryphon Audio Designs elevates pure Class A power amplification a titanic leap above what was previously considered possible. The Gryphon Apex takes us several crucial steps closer in the never-ending quest for a more natural and convincing musical illusion.
Years of experience developing the Antileon EVO and Mephisto power amplifiers, as well as ongoing research in the fields of circuit topology, component quality and reliability have culminated in the Gryphon Apex: the new flagship amplifier of the Gryphon Audio Designs brand.
The material specifications of the Gryphon Apex illustrate its cost-no-object design: The Gryphon Apex Mono features a staggering complement of 128 very high-current bipolar output transistors (64 per chassis), 2.080.000 μF (>2 Farad) capacitor banks (>1 Farad per chassis), four separate custom-made 2,000 VA toroidal transformers (two per chassis), all housed in a magnificently crafted, constrained-layer-damped chassis. The Gryphon Apex Stereo tips the scales at 202kg (nearly 450 pounds), while a pair of Apex Mono weigh-in at 404kg (900 pounds)!
Given the massive power reserves available at all times, Gryphon Apex amplifiers simply do not “see” the loudspeaker; in other words, Apex’ virtually limitless reservoir of power and current renders it immune to loudspeaker characteristics. No speaker load, no matter how reactive, can affect Apex’ performance. This means that Apex always delivers its ultimate sound quality, regardless of loudspeaker choice. What’s more, unlike other high-power amplifiers, Gryphon’s no-compromise, pure Class A topology offers this prodigious power combined with ultimate refinement and delicacy in musical presentation.
It is Gryphon’s fundamental philosophy that all electronics in the playback chain should strive for neutrality, neither adding nor subtracting anything from the recording, no matter how “pleasing” such distortions may be. The Gryphon Apex is by nature a product for the fortunate few who can afford such a statement: a product for the connoisseurs who seek absolute purity in the reproduction of music. In short, Apex has been created for music lovers whose respect for the musicians, producers and mastering engineers inspires them to seek the truth lurking in the original recording.
