It combines a precision FPGA-controlled clocking system, a discrete Class-A analog stage, and a built-in network streamer with Roon, AirPlay, and UPnP support – a versatile high-resolution centerpiece for any desktop or speaker system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual ES9039SPRO DAC Chips\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach stereo channel is powered by its own ES9039SPRO chip with independent power supplies and grounding. This architecture maintains superior channel separation, reduces crosstalk, and sharpens imaging precision, so instruments and voices occupy clear, distinct spaces in the soundstage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBuilt-in Network Streamer \u0026amp; USB Interface\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA LAN port (100\/1000 Mbps) running the CelWare 3.x platform supports Roon\/Roon Bridge, AirPlay, UPnP, Spotify, HQPlayer NAA, and more, giving direct access to streaming services and local libraries. The USB-B input is driven by the XMOS XU216 chip, supporting PCM up to 768kHz, native DSD512, and MQA decoding.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePrecision Clocking \u0026amp; FPGA Control\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe GCLK-02 clock module with a femtosecond-grade clock generator minimizes jitter for cleaner audio timing, and a dedicated 10MHz BNC input accepts an external master clock.
