About This

• Audiophile-Grade DAC Architecture: Built around the ES9039Q2M, this USB-C dongle DAC/amp supports 32-bit/768 kHz PCM and native DSD512, delivering a ≥122 dB SNR and <0.0003% THD—while outputting 220 mW @ 32Ω balanced. Engineered for transparent, low-noise reproduction with efficient power draw, it pairs flawlessly with phones, PCs, and the Switch for reference-grade listening on the go.
• XMOS-POWERED Dual-Core Processing: As the world’s first battery-free DAC/amp to integrate XMOS POWERED, DS3 runs a 1.6 GHz dual-core engine that fully unlocks the ES9039Q2M’s capabilities. This ensures bit-perfect, jitter-free audio streaming from source to decoder, with future firmware upgradability to keep performance evolving—no external power brick required.
• Hardware-Backed Spatial Enhancement: A built-in Fosi algorithm transforms multichannel audio into an immersive 360° soundscape, while a dedicated positional cue enhances directional clarity—ideal for critical listening and content consumption on PC, PS5, or Switch. Plug-and-play, driver-free across all platforms.
• Hi-Fi-Centric Dual Modes & Advanced EQ: Supports both UAC 1.0 and UAC 2.0 with independent volume memory. Fine-tune your sound with 8 selectable digital filters and a 32-band hardware-level PEQ—adjustable via an intuitive web-based control panel—delivering precise, phase-coherent customization without any sonic degradation. This is reference-grade tone shaping, not software emulation.
• Reference Tuning & Dynamic Fidelity: Engineered for highly neutral, faithful reproduction with exceptional dynamic range and transient response, the DS3 stays true to the original recording. Whether driving sensitive IEMs or demanding full-size headphones, it reveals micro-details without artificial coloration—perfect for mix reference and critical listening.
• Refined Industrial Design: CNC-milled aerospace aluminum and a tempered-glass skylight keep the portable dongle at just 16 g, offering a premium tactile feel while showcasing the precision-laid internal circuitry. Available in Galaxy and Obsidian finishes, matching the IM4 headphones for a cohesive aesthetic.
• Important Note: The DS3 is a dedicated Hi-Fi DAC/amp—it does not include a built-in microphone, ensuring a pure, unadulterated audio path with no signal cross-contamination.
