The Pinnacle of High-End Amplification | Available at Trimira Audio
The Gryphon Apex Solo Mono Power Amplifier is the monoblock expression of Gryphon's flagship Apex amplification platform, designed for uncompromising reference two-channel systems where maximum current delivery, dynamic authority, and loudspeaker control are paramount.
Operating in Pure Class A with zero global negative feedback, the Apex Solo employs a parallel monoblock architecture, with two amplifier stages operating in parallel within each dedicated chassis. This architecture is designed to increase current capability and reduce output impedance while maintaining the sonic characteristics of Gryphon's flagship Class A design.
A matched pair is specified to deliver 225 W into 8 Ω, 450 W into 4 Ω, 900 W into 2 Ω, and 1,800 W into 1 Ω per channel.
At Trimira Audio, we recommend the Apex Solo Mono for the most demanding reference loudspeakers and installations where amplifier scale, current delivery, and system control are uncompromising priorities.
Key Features & Technological Innovations
Parallel Monoblock Architecture
Each Apex Solo incorporates two complete amplifier stages operating in parallel within its dedicated chassis.
The architecture is designed to increase available current while reducing output impedance, providing exceptional control over demanding loudspeaker loads.
Unlike a conventional bridged configuration, the parallel approach is intended to retain the amplifier's current-delivery characteristics while increasing output capability.
Pure Class A Operation
The Apex Solo operates in Pure Class A and provides substantial power across progressively lower impedances:
- 225 W @ 8 Ω
- 450 W @ 4 Ω
- 900 W @ 2 Ω
- 1,800 W @ 1 Ω
This makes the amplifier particularly suited to reference loudspeakers with challenging impedance characteristics.
2,080,000 µF Total Energy Storage
A matched stereo pair incorporates a remarkable 2,080,000 µF total power-supply reservoir, equivalent to more than two farads of capacitance.
The substantial energy-storage capacity is designed to provide significant power reserves during demanding transient events.
128 High-Current Bipolar Output Transistors
Across the stereo pair, the Apex Solo system incorporates 128 high-current bipolar output devices.
The extensive parallel output architecture is designed to provide substantial instantaneous current capability while maintaining control over low-impedance loudspeaker loads.
Quad 2,000 VA Transformer Architecture
A pair of Apex Solo monoblocks incorporates four custom 2,000 VA toroidal transformers.
The transformers are housed in shielded, mechanically decoupled structures designed to minimise magnetic interaction, mechanical vibration, and unwanted mains-related interference.
Green Bias Control
The Apex Solo incorporates Gryphon's Green Bias system, with selectable Low, Mid, and High manual bias settings.
When connected to compatible Gryphon preamplification, the Green Bias link can provide automated bias management according to system operating conditions.

Reference Monoblock System Architecture
A matched pair provides dedicated amplification for each loudspeaker:
Preamplifier → Left Apex Solo → Left Loudspeaker
Preamplifier → Right Apex Solo → Right Loudspeaker
Each chassis has its own power infrastructure, while the parallel internal amplifier architecture provides additional current capability.
This configuration is particularly appropriate for large reference loudspeakers with complex impedance curves or demanding dynamic requirements.
High-Current Loudspeaker Matching
The Apex Solo's specified output scales substantially with decreasing impedance:
| Load | Output per Channel |
|---|---|
| 8 Ω | 225 W |
| 4 Ω | 450 W |
| 2 Ω | 900 W |
| 1 Ω | 1,800 W |
When matching the Apex Solo to a reference loudspeaker, Trimira Audio can evaluate:
- Sensitivity
- Minimum impedance
- Phase angle
- Room size
- Listening distance
- Desired playback levels
- Current requirements
Installation & Thermal Management
At 202 kg per chassis, a pair of Apex Solo monoblocks requires serious logistical and installation planning.
Pure Class A operation also produces substantial heat, making adequate ventilation essential.
Trimira Audio can advise on:
- Dedicated 20 A AC circuits
- Equipment support
- Safe positioning
- Amplifier spacing
- Ventilation
- Thermal management
- Green Bias configuration
- Balanced XLR system integration
The physical installation should be planned before delivery to ensure appropriate access and equipment support.
