The ESS ES9069Q DAC with HyperStream IV Dual DAC architecture delivers +130dB dynamic range and -120dB THD+N. A quad balanced drive architecture featuring dual TI OPA1602 op-amps and dual SGM8262 amplifiers produces 560mW + 560mW per channel (4.4mm balanced, Hyper Mode). Supporting PCM 768kHz/32-bit and native DSD512 via SPV5068 RISC-V processor, the RU3 works across all platforms. Precision-machined from aerospace-grade aluminium (60 × 25.4 × 11mm, 24g), it features a 0.96-inch IPS display, dual power modes, and the Cayin Control App with 10-band parametric EQ.
