Compact USB-C DAC and headphone amp for daily listening Meet the Uno: a pocket-sized USB-C DAC and headphone amplifier designed to enrich your everyday audio—whether you're streaming music, watching movies, or gaming. With True‑Native decoding, selectable EQ modes, and plenty of power, it empowers your headphones or powered speakers with clear, nuanced sound. ESS Sabre DAC for True‑Native Playback At its core is the ESS ES9219MQ/Q DAC with HyperStream III and Quad DAC+ architecture, delivering bit-perfect support for PCM up to 384 kHz, DSD256, DXD, and MQA. It preserves timing, detail, and dynamic range without oversampling or DSP manipulation. Tailored Power and Analog Volume The headphone output offers up to 211 mW at 32 Ω and 39 mW at 300 Ω—enough to drive a wide range of headphones—while S‑Balanced analog volume control maintains audio resolution at all levels. PowerMatch ensures optimal gain settings for different headphones. Mode-Specific EQ for Music, Movies & Gaming One‑touch EQ switching lets you choose preset curves: Music for balanced clarity, Movie for highlighted dialogue, and Game for precise spatial cues. Advanced filter options—Standard, Minimum‑Phase, Bit‑Perfect—are accessible via long‑press EQ control, giving you sonic flexibility. Pure Analog Audio Path Analog S‑Balanced headphone output and gold‑plated RCA line output reduce noise and crosstalk. Volume control and gain switching are entirely analog, so turning the volume down doesn’t remove audio data. USB‑C Convenience & Compact Design Powered via USB‑C (no wall adapter needed), UNO draws both digital audio and power from your device. Rugged mineral‑filled polymer shell with an aluminum front panel fits in your palm and blends into any desktop.
