Legendary Dual-Mono Analog Performance | Available at Trimira Audio
The Gryphon PS2-S MM/MC Phono Module is an internal phono-stage upgrade designed to bring high-end vinyl playback directly into compatible Gryphon integrated amplifiers and preamplifiers.
Developed from Gryphon's phono-stage engineering heritage, the PS2-S combines true dual-mono Class A circuitry, zero global negative feedback, discrete matched transistor arrays, precision circuit-board construction, and flexible cartridge loading.
Its internal architecture eliminates the need for a separate phono-stage chassis, external power supply, and additional interconnect between the phono stage and host preamplifier.
At Trimira Audio, we recommend the PS2-S for Gryphon owners seeking sophisticated MM/MC vinyl playback while maintaining a clean, integrated system architecture.
Key Features & Technological Innovations
True Dual-Mono Class A Circuitry
The PS2-S uses independent left- and right-channel analogue circuits.
This dual-mono architecture is designed to maximise channel separation and maintain consistent signal handling between both channels.
Zero Global Negative Feedback
The module operates without global negative feedback.
Its discrete signal circuitry is designed to preserve transient behaviour and harmonic information throughout the low-level phono signal path.
Extended MC Cartridge Loading
The PS2-S provides multiple selectable MC load values, including:
- 20 Ω
- 100 Ω
- 200 Ω
- 499 Ω
- 806 Ω
Additional custom values can be supported according to system configuration.
This flexibility allows the module to be matched closely to the electrical characteristics of different low-output Moving Coil cartridges.
Selectable MM & MC Operation
The module provides two primary gain configurations:
Internal configuration allows the gain stage to be set according to the cartridge type.
Direct Internal Integration
The PS2-S installs directly into a compatible Gryphon expansion bay.
This provides:
- Short internal signal paths
- No additional external chassis
- No separate phono-stage power cable
- Direct integration with the host component
Gold-Plated RCA Inputs
The module provides dedicated gold-plated RCA phono inputs with Teflon insulation, together with a dedicated cartridge ground connection.
This provides a straightforward interface for conventional single-ended tonearm wiring.

Cartridge Matching
The PS2-S is particularly useful when cartridge loading needs to be optimised carefully.
For Moving Coil cartridges, the selectable resistance values allow the loading to be matched to the cartridge manufacturer's recommendations and the rest of the analogue system.
Trimira Audio can assist with:
- MC load selection
- MM capacitance matching
- Cartridge output-level assessment
- MM/MC gain selection
- Tonearm compatibility
- Grounding
- RIAA system configuration
Reference Vinyl System Integration
The internal module allows a compatible Gryphon component to become the centre of a streamlined analogue system:
Turntable → Tonearm / Cartridge → PS2-S → Gryphon Preamplifier / Integrated Amplifier → Power Amplifier → Loudspeakers
This approach avoids the additional chassis and interconnect required by an external phono stage.
For high-resolution vinyl systems, correct cartridge loading, gain, grounding, and tonearm setup remain essential.
Compatible Gryphon Platforms
The PS2-S is specified for compatibility with:
- Gryphon Diablo 120
- Gryphon Diablo 300
- Gryphon Essence
- Gryphon Zena
Compatibility and installation requirements should be confirmed for the specific host component before ordering.
Professional Installation & Setup
Because the PS2-S is an internal expansion module, installation should be performed by an appropriately qualified technician.
Trimira Audio can assist with:
- Module installation
- MM/MC configuration
- Cartridge loading
- Gain selection
- Grounding
- Turntable and tonearm setup
- Final analogue-system calibration
