Gryphon Antileon Revelation Stereo Class A power amplifier

Gryphon Antileon Revelation power amplifier

Technical excellence in its latest form: To mark Gryphon Audio Designs' 40th anniversary, the Antileon Revelation celebrates its premiere – the most advanced version of the legendary amplifier to date.

Building on the technological heritage of the DM-100 introduced in 1991, the Revelation combines modern engineering with Gryphon's signature design principles:

• uncompromising dual-mono architecture
• pure Class A circuit and
• highest performance reserves.

Technical highlights at a glance:

Optimized power supply: Two separate, specially designed 1150 VA toroidal transformers per chassis ensure a stable and powerful power supply. An additional, independent power supply precisely controls the digital electronics—decoupled from the audio signal path.

Massive power reserves: A total of 40 Toshiba high-current bipolar transistors per chassis – identical to those in the Gryphon Apex – as well as an impressive 670,000 µF filter capacitance enable confident control over any speaker load.

New connection components: The rear panel has been equipped with custom-made Gryphon speaker terminals and two 20A mains connectors, ensuring loss-free power supply at maximum performance.

Design meets function: The high-quality metal craftsmanship of the Antileon EVO remains intact. A new addition is a striking Gryphon sculpture that covers the transformer as a decorative and protective element.

Operational flexibility: The Antileon Revelation is available as a stereo version with 165 W per channel and as a mono version with 180 W – each in pure Class A operation for maximum sonic purity.

The Antileon Revelation redefines the standard: with increased dynamics, an even deeper bass foundation, airier highs and a three-dimensional sound image that impresses with its technical sophistication.
