This reference-grade high-resolution Discrete R-2R Ladder DAC & Network Streamer combines traditional resistor ladder architecture with modern network streaming and master clock synchronisation[cite: 1]. Designed for uncompromising digital audio performance, it features a discrete R-2R DAC ladder network alongside a specialized Sony 1-Bit Direct DSD conversion circuit for pure, native DSD processing[cite: 1].
The unit incorporates a K2 ultra-low noise clock synthesizer with a 10MHz Master Reference Clock input, ensuring precise digital timing and minimal jitter[cite: 1]. Signal conversion is powered by a discrete 8-channel hybrid I/V power conversion circuit tailored for R-2R ladder architectures[cite: 1]. Equipped with an integrated Gigabit LAN streaming module, it supports Roon Ready, AirPlay, UPnP, NAA (Signalyst Network Audio Adapter), and Spotify Connect with online firmware upgrade capability[cite: 1].
