Reference Digital Performance in a Single Chassis | Available at Trimira Audio
The Gryphon Zena DAC Module is an internal digital-conversion upgrade designed for compatible Gryphon preamplifiers and modular line-stage platforms.
By integrating high-resolution D/A conversion directly into the host preamplifier, the module avoids the need for a separate DAC chassis and additional analogue interconnects. Its architecture combines ESS Sabre ES9018 conversion, dual-mono analogue circuitry, Pure Class A output buffering, and extensive USB power isolation.
The module supports PCM up to 32-bit/384 kHz and native DSD512 through USB, making it suitable for high-resolution computer-audio and digital-streaming systems.
At Trimira Audio, we recommend the Zena DAC Module for Gryphon owners seeking a compact, highly integrated digital front end while retaining the preamplifier's existing chassis and system architecture.
Key Features & Technological Innovations
ESS Sabre ES9018 Dual-Mono Architecture
The module uses the ESS Sabre ES9018 32-bit DAC in a balanced dual-mono configuration.
The architecture is designed to provide high dynamic range, low distortion, and strong channel separation.
12.5-Farad SuperCap USB Power Supply
A dedicated 12.5 F SuperCap power supply isolates the USB receiver from the host computer's power supply.
This acts as an energy-storage buffer for the USB interface and is designed to reduce unwanted power-line noise entering the digital conversion circuitry.
Discrete Pure Class A Analogue Output
The analogue section uses a fully discrete Pure Class A output stage operating without global negative feedback.
The output circuitry uses regulated ±22 VDC rails to provide a substantial voltage supply for the analogue stage.
High-Resolution PCM & DSD
Through asynchronous USB, the Zena DAC Module supports:
- PCM up to 32-bit / 384 kHz
- Native DSD64
- Native DSD128
- Native DSD256
- Native DSD512
The S/PDIF inputs support PCM up to 24-bit/192 kHz, with optical supporting up to 24-bit/96 kHz.
Selectable Digital & Analogue Filters
The module provides user-selectable PCM filter characteristics, including fast and slow roll-off options.
DSD playback also provides selectable analogue filtering at 50 kHz, 60 kHz, or 70 kHz.
This allows the digital output characteristics to be tailored to the listener's preference and system.
Shielded Internal Housing
The DAC circuitry is housed within an independently grounded aluminium enclosure.
The shielded construction is designed to minimise RF and electromagnetic interaction between the digital module and the sensitive analogue circuitry of the host preamplifier.

Digital System Integration
Once installed, the Zena DAC Module can turn a compatible Gryphon preamplifier into a highly integrated digital control centre.
A typical configuration is:
Computer / Streamer → Zena DAC Module → Gryphon Preamplifier → Power Amplifier → Loudspeakers
The internal architecture eliminates the need for a separate external DAC and its associated analogue interconnect.
For systems using dedicated transports, the BNC, AES/EBU, and optical inputs provide additional connectivity options.
Computer Audio & DSD Playback
USB provides the module's highest specified digital capability, including 32-bit/384 kHz PCM and native DSD512.
The asynchronous USB interface is designed for computer-based playback, while the SuperCap supply provides additional isolation between the USB receiver and the computer's power system.
