Built around the 3rd-generation XMOS XU316 processor with SMSL's proprietary CK-02 ultra-low-jitter clock circuit, supporting PCM up to 192 kHz, DOP64 (DSD64), and full MQA decoding without requiring specialized playback software, the PO100 delivers bit-perfect, low-noise digital conversion in a pocket-sized 75-gram aluminum chassis that weighs less than a smartphone.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eXMOS XU316 with CK-02 Clock Circuit\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 3rd-generation XMOS XU316 processor provides asynchronous USB transmission for jitter-free data transfer, while SMSL's CK-02 clock circuit dramatically reduces timing errors at the output stage. The result is coaxial and optical digital outputs with vanishingly low clock jitter — delivering a pristine, stable bitstream to your external DAC.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFull MQA Decoding Without Specialized Software\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUnlike many USB interfaces that require foobar2000, Audirvana, or other specialized media players for MQA playback, the PO100 handles MQA decoding natively. Simply use any audio application with ASIO or WASAPI output, and the PO100 unfolds MQA-encoded content with studio-authenticated precision.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eOptical and Coaxial Outputs with DOP64 Support\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth optical (TOSLINK) and coaxial (RCA) digital outputs support sampling rates from 44.1 kHz to 192 kHz, plus DOP64 for DSD64 transport. Connect the PO100 to any DAC with SPDIF inputs to add high-quality USB connectivity without replacing your existing digital components.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eUSB-C Input with Broad Compatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA modern USB-C input connects to computers, phones, tablets, and USB-enabled streamers and players. Compatible with Windows (10 and above, driver-free; earlier versions require a driver), macOS (driver-free), Android, iOS, and Linux.

The result is a cleaner, quieter signal reaching your DAC — with demonstrably improved fidelity.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompact, Portable, 75 Grams\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWeighing only 75 grams including packaging and measuring smaller than most smartphones, the PO100 disappears into any desktop or portable audio setup.
