Reference Dedicated Monoblock Class A Power Amplifiers | Trimira Audio Specialist
The Gryphon Antileon Revelation Mono pair represents the ultimate monoblock expression of Gryphon's renowned Antileon amplifier architecture.
Each amplifier operates as a completely independent single-channel power amplifier, with its own power supply, transformer assembly, output stage, and chassis. This approach maximises channel separation while providing substantial current reserves for demanding loudspeaker loads.
Operating in Pure Class A with zero global negative feedback, each monoblock delivers 180 W into 8 Ω, 360 W into 4 Ω, and 720 W into 2 Ω.
At Trimira Audio, we recommend the Antileon Revelation Mono pair for reference two-channel systems requiring exceptional current capability, channel isolation, dynamic authority, and the distinctive presentation of pure Class A amplification.
Key Features & Audio Engineering Highlights
Dedicated Single-Channel Monoblock Architecture
Each Antileon Revelation Mono is a completely independent amplifier.
By separating the left and right channels into individual chassis, the design eliminates the need for shared power-supply and output-stage resources, maximising electrical isolation between the two channels.
Pure Class A & Zero Global Negative Feedback
The amplifier operates continuously in Pure Class A and uses 0 dB global negative feedback.
This topology is designed to avoid conventional crossover distortion while maintaining a wide-bandwidth, direct signal path.
80 High-Current Bipolar Output Transistors
Each monoblock incorporates 80 high-current Toshiba bipolar output transistors operating in parallel.
The substantial output stage is designed to provide high instantaneous current capability and maintain control as loudspeaker impedance decreases.
The specified output impedance is just 0.02 Ω.
670,000 µF Power-Supply Reservoir
Each monoblock incorporates a massive 670,000 µF power-supply capacitor reservoir.
Across a matched pair, the total reservoir capacity reaches:
1,340,000 µF
Each amplifier also incorporates 2 × 1,500 VA custom toroidal transformers, providing dedicated power infrastructure for each channel.
Selectable Class A Bias & Green Bias
The Antileon Revelation Mono provides Low, Medium, and High Class A bias settings.
Gryphon's Green Bias system can also be linked to a compatible Gryphon preamplifier, allowing operating bias to respond to playback requirements.
This provides flexibility in balancing Class A operating range, heat generation, and power consumption.
Upgraded Signal Path
The amplifier incorporates:
- BJT input-buffer stages
- Solid-core silver internal signal wiring
- Double-sided copper PCBs
These elements form part of Gryphon's high-current, low-noise amplifier architecture.

High-Current Loudspeaker Matching
The Antileon Revelation Mono is designed to maintain increasing power output as loudspeaker impedance falls:
- 180 W @ 8 Ω
- 360 W @ 4 Ω
- 720 W @ 2 Ω
This makes the monoblocks particularly attractive for demanding loudspeakers with difficult impedance characteristics.
When selecting a matching loudspeaker system, Trimira Audio can assess:
- Sensitivity
- Nominal and minimum impedance
- Phase angle
- Room size
- Desired listening levels
- Amplifier current requirements
Reference Two-Channel Architecture
A matched pair provides a completely independent power-amplifier path for each loudspeaker:
Left Channel: Preamplifier → Antileon Revelation Mono → Left Loudspeaker
Right Channel: Preamplifier → Antileon Revelation Mono → Right Loudspeaker
This physical separation can be particularly valuable in high-resolution stereo systems where channel isolation and independent power delivery are priorities.
Installation & Thermal Management
Pure Class A operation generates considerable heat, particularly when using the higher bias settings.
Each 90 kg amplifier also requires a suitably strong and stable equipment platform.
Trimira Audio can advise on:
- Dedicated 20 A mains circuits
- Equipment support
- Amplifier spacing
- Ventilation
- Thermal management
- Green Bias configuration
- Balanced XLR system integration
