384KHz Low-Distortion DAC Amp

Engineered for accuracy and transparency, this USB-C DAC amplifier uses the CX31993 DAC chip and MAX97220 op-amp to achieve 32-bit/384 kHz PCM decoding and ultra-low distortion performance. Measured THD+N is 0.0003%, with >128 dB SNR and >120 dB DNR. Housed in a precision-machined metal casing (approx. 6.5 × 2.2 × 1.3 cm, ±1–3 cm tolerance), it weighs ~42 g. Supports DSD64 and DSD128 via PCM conversion. Includes one main USB-C to 3.5 mm unit and one auxiliary USB-A to USB-C adapter (colour varies). Designed specifically for UK listeners who value measurable performance metrics and audible improvements over OEM smartphone audio — especially with planar magnetic or high-sensitivity earphones.
