Gryphon Essence Mono

Dedicated Monoblock Class A Reference Power Amplifiers | Trimira Audio Specialist

The Gryphon Essence Mono is a dedicated single-channel power amplifier designed to provide the isolation, current delivery, and Class A performance of a true monoblock system.

Operating in pure Class A with zero global negative feedback, each Essence Mono has its own power supply, output stage, and chassis. A matched pair therefore provides complete left/right amplifier separation, making it an ideal foundation for demanding high-end two-channel systems.

At Trimira Audio, we recommend the Gryphon Essence Mono pair for listeners seeking exceptional channel separation, refined Class A performance, substantial current capability, and precise control of demanding loudspeakers.

Key Features & Audio Engineering Highlights

Dedicated Monoblock Pure Class A Architecture

Each Essence Mono is designed as a single-channel amplifier, eliminating the need to share the power supply and output stage between left and right channels.

The pure Class A topology avoids conventional crossover distortion, while zero global negative feedback preserves the amplifier's direct signal architecture.

20 High-Current Bipolar Output Transistors

Each monoblock incorporates 20 high-current Sanken bipolar output transistors operating in parallel.

The substantial output stage provides significant current capability and contributes to the exceptionally low specified output impedance of 0.0075 Ω.

440,000 µF Power Reservoir per Monoblock

Each Essence Mono contains a dedicated 440,000 µF capacitor bank supported by a custom 1350 VA shielded toroidal transformer.

Across a matched stereo pair, this represents:

The independent power supplies maintain complete electrical separation between the two channels.

Green Bias Control System

The Essence Mono incorporates Gryphon's Green Bias system with Low, Mid, and High Bias settings.

The bias system allows Class A operation to be adjusted according to system requirements and listening conditions, while a compatible Gryphon preamplifier can provide linked control.

A DC-coupled signal path with servo circuitry provides a specified bandwidth of:

0.3 Hz–350 kHz (+0, −3 dB)

The exceptionally wide response provides substantial bandwidth beyond the audible range.

Microprocessor Protection

The amplifier continuously monitors operating conditions including:

• DC offset
• Short circuits
• Temperature

The protection system is designed to safeguard the amplifier and loudspeakers without placing conventional relays or fuses directly in the primary audio signal path.

Product Specifications

Reference Two-Channel System Integration

A pair of Essence Monoblocks provides complete left/right channel separation:

Preamplifier → Left Essence Mono → Left Loudspeaker

Preamplifier → Right Essence Mono → Right Loudspeaker

This architecture can be particularly attractive for reference systems where physical separation of the power amplifiers and independent power supplies are important design priorities.

With 55 W into 8 Ω, 110 W into 4 Ω, and 220 W into 2 Ω, the Essence Mono is capable of delivering increasing power into lower impedance loads.

Loudspeaker sensitivity and impedance characteristics should nevertheless be considered carefully when selecting the amplifier for a particular system.

Class A Installation Requirements

Pure Class A operation generates considerable heat, particularly at higher bias settings.

The pair should therefore be installed with sufficient ventilation and clearance around each chassis.

Trimira Audio can advise on:

• Equipment-rack placement
• Amplifier spacing
• Ventilation
• Dedicated AC power
• Green Bias settings
• Loudspeaker matching
