This reference-grade Network DAC & Streamer features a discrete R2R DAC topology alongside a dedicated Sony 1-Bit Direct DSD conversion circuit. Equipped with K2 Technology ultra-low noise clock synthesis, an integrated Roon Bridge network streaming engine, and support for 10M master clock inputs, it delivers exceptional dynamic range, ultra-low distortion, and superior channel separation for high-end digital audio systems.
KEY FEATURES
- 10M Master Reference Clock Input: Accepts external 10MHz master clock inputs for ultra-precise timing synchronization.
- K2 Technology Ultra Low Noise Clock Synthesizer: Eliminates digital jitter and timing artifacts across all digital inputs.
- Discrete R2R DAC: Uses a precision resistor ladder network for continuous, natural, and highly detailed analog reconstruction.
- Sony 1-Bit Direct DSD Conversion Circuit: Dedicated hardware path for pure 1-bit direct DSD decoding without PCM conversion.
- Roon Bridge Network Streaming: Built-in multi-protocol network module supporting hi-res streaming across home networks.
- Discrete 8-Channel Hybrid I/V Stage: Fully discrete hybrid current-to-voltage power conversion circuit designed specifically for the R2R architecture.
