The Pinnacle of Integrated Amplification | Available at Trimira Audio
The Gryphon Diablo 333 Integrated Amplifier is the successor to the renowned Diablo 300, bringing technologies derived from Gryphon's flagship preamplifier and power-amplifier platforms into a single high-performance chassis.
Built around a true dual-mono architecture, the Diablo 333 combines a sophisticated analogue preamplifier section with a high-current power stage, precision relay volume control, modular digital and phono expansion, and extensive system connectivity.
With specified output of 333 W per channel into 8 Ω, 666 W into 4 Ω, and 1,100 W into 2 Ω, the Diablo 333 is engineered to provide substantial control over demanding loudspeaker loads.
At Trimira Audio, we recommend the Diablo 333 for listeners seeking the performance and system simplicity of a flagship integrated amplifier without separating the preamplifier and power amplifier into multiple chassis.
Key Features & Technological Innovations
Apex & Commander-Derived Technology
The Diablo 333 incorporates circuit technologies derived from Gryphon's flagship Apex power amplification and Commander preamplification platforms.
The design uses high-speed pre-driver and output-stage devices developed for Gryphon's reference amplification architecture.
True Dual-Mono Construction
The amplifier employs independent left- and right-channel architecture supported by substantial power-supply resources.
Two 68,000 µF capacitor banks provide a combined 136,000 µF of filter capacitance.
This arrangement is designed to maximise channel separation and provide stable power delivery during demanding musical transients.
43-Step Relay Volume Attenuator
Volume is controlled through a 43-step microprocessor-controlled relay attenuator using precision resistors.
The architecture is designed to provide accurate channel tracking while maintaining a controlled analogue signal path.
4.3-Inch TFT Touchscreen
A 4.3-inch TFT capacitive touchscreen sits behind a 4 mm hardened-glass interface.
The display provides access to system functions including:
- Input selection
- Input level matching
- Display settings
- Module configuration
- System control
Modular DAC & Phono Expansion
Two internal expansion bays provide support for optional Gryphon modules, including:
- DAC3 ES9039PRO D/A Module
- PS3 True Dual-Mono MM/MC Phono Module
This allows the Diablo 333 to function as the central component of a sophisticated digital and analogue system.
Zero Global Negative Feedback
The Diablo 333 uses zero global negative feedback and provides a specified 0.1 Hz–350 kHz (-3 dB) bandwidth.
The architecture is designed to provide wide-bandwidth operation and controlled transient response.
Comprehensive Connectivity
The Diablo 333 provides extensive system integration options, including:
- Balanced XLR inputs
- RCA inputs
- Tape input/output
- Dual subwoofer outputs
- Fixed-level AV throughput
- Heavy-duty Gryphon loudspeaker terminals
This makes the amplifier suitable for both dedicated two-channel systems and hybrid music/home-cinema installations.

High-Current Loudspeaker Matching
The Diablo 333's power output scales substantially as impedance decreases:
| Load |
Output per Channel |
| 8 Ω |
333 W |
| 4 Ω |
666 W |
| 2 Ω |
1,100 W |
This makes the amplifier particularly suitable for high-performance loudspeakers that present demanding impedance curves.
When selecting a loudspeaker partner, Trimira Audio can evaluate:
- Sensitivity
- Minimum impedance
- Phase angle
- Room size
- Listening distance
- Desired playback levels
- Current requirements
Integrated Digital & Analogue System
With the optional modules installed, the Diablo 333 can serve as the central hub for a complete high-end system.
A possible configuration is:
Digital Sources / Streaming → DAC3 → Diablo 333 → Reference Loudspeakers
and:
Turntable → PS3 Phono Module → Diablo 333 → Reference Loudspeakers
This approach provides substantial system functionality while retaining a single primary electronics chassis.
Home-Cinema Integration
The Diablo 333's selectable fixed-level AV throughput allows it to participate in a hybrid stereo and home-cinema installation.
The integrated subwoofer outputs also provide straightforward connection to powered subwoofers where additional low-frequency extension is required.
Trimira Audio can assist with:
- AV bypass configuration
- Stereo/home-cinema integration
- Subwoofer connection
- DAC3 installation
- PS3 phono configuration
- System gain management
Installation & System Matching
At 50.6 kg, the Diablo 333 requires a suitably robust equipment platform.
Its high-power output stage also makes appropriate ventilation and mains infrastructure important considerations.
Trimira Audio can advise on:
- Equipment support
- Ventilation
- Dedicated AC power
- Loudspeaker matching
- Balanced versus single-ended connectivity
- Module configuration
- Complete system installation
