The DENAFRIPS Hermes 15th Anniversary Edition is a mid-to-high-end Digital-to-Digital Converter (DDC) engineered to cleanse, reclock, and reformat digital audio bitstreams for reference-grade DACs. Celebrating DENAFRIPS' 15th anniversary, this updated model replaces the original steel enclosure with a precision CNC-machined, fine-brushed anodized aluminum chassis, offering vastly superior vibration damping, electromagnetic shielding, and thermal management.

At its core, the Hermes 15th utilizes a proprietary FPGA DSP Processing Architecture paired with a FIFO buffer system and dual Oven Controlled Crystal Oscillators (OCXO) for ultra-low-jitter clock re-timing. Optically isolated digital inputs—driven by an STM32F446 ARM-based USB interface—prevent host noise from entering the signal path. Powered by an oversized 80VA UPOCC copper O-Core linear transformer, the Hermes 15th outputs clean digital signals via dual AES/EBU, Coaxial S/PDIF, TOSLink, and both HDMI LVDS and RJ45 LVCMOS I²S outputs, with support for external 45.1584MHz / 49.152MHz master clock inputs.

KEY FEATURES & PROPRIETARY TECHNOLOGIES

• CNC Machined Aluminum Chassis: Precision-milled, fine-brushed anodized aluminum housing that significantly increases structural rigidity, thermal dissipation, and resonance control.
• FPGA DSP Architecture & FIFO Reclocking: Digital signals are buffered in FIFO RAM and reclocked using dual Oven Controlled Crystal Oscillators (OCXO) to eliminate timing jitter.
• Optical Isolation on All Inputs: Full galvanic optical isolation across all digital input stages protects audio signals from computer noise and ground loops.
• STM32F446 ARM-Based USB Audio Solution: High-speed proprietary USB processing engine supporting up to PCM 768kHz and native DSD512.
• 80VA UPOCC Copper O-Core Transformer: Heavy-duty linear power supply incorporating Ultra-Pure Ohno Continuous Cast copper windings for clean, ripple-free power delivery.
• Dual I²S & Dual AES/EBU Outputs: Features both HDMI LVDS and RJ45 LVCMOS I²S pinouts alongside dual AES/EBU balanced digital outputs for extreme system flexibility.
• External Master Clock Input: Accepts external 45.1584MHz and 49.152MHz clock sync inputs from master clock generators.
