Cayin Presents The Latest Addition To Their RU Series of DAC & Amp - The RU3
Cayin revolutionised portable audio with the acclaimed RU series before extending this legacy into accessible territory with the RU3. 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 Graphical EQ for an extraordinary listening experience.
Features ESS ES9069Q DAC with HyperStream IV Architecture
The ESS ES9069Q employs HyperStream IV Dual DAC technology, delivering +130dB dynamic range and -120dB THD+N. Dual independent signal paths maintain precise channel balance and eliminate crosstalk. Independent op-amp stages, dedicated LDO power system, and ultra-low phase noise crystal oscillator ensure pinpoint signal precision. Eight preset digital filters plus programmable options allow reconstruction customization.
Powerful Amplification With Quad Balanced Amplifier with Dual Power Modes
The quad balanced amplifier uses TI OPA1602 op-amps and SGM8262 ultra-low noise amplifiers (3.5nV/√Hz, 110dB gain). Hyper Mode delivers 560mW + 560mW (32Ω, balanced), while Standard Mode reduces power for efficient operation. Output impedance: 0.6Ω (SE), 1.2Ω (BAL).
Experience High-Resolution Decoding with RISC-V Processor
The SPV5068 RISC-V dual-core bridge enables PCM 32-bit/768kHz and native DSD512. UAC2.0 compliant, plug-and-play across all platforms. Measured specs: SNR 115dB (SE)/117dB (BAL), THD+N 0.0018% (SE)/0.0015% (BAL).
Intelligent Control With Cayin App And High-Precision Lossless Graphical EQ
Cayin RU3 integrates seamlessly with the Cayin Control App, offering intuitive control over key audio functions. Users can fine-tune output mode, channel balance, digital filters, and access a 10-band high-precision lossless Graphical EQ for shaping their sound signature. Multiple EQ profiles can be saved, recalled, and customised for any genre or mood. Regular firmware updates ensure ongoing feature improvements, giving listeners a future-ready experience through a simple, responsive interface.
Showcases Premium Aluminum Design and RU Series Heritage
CNC-machined from aerospace-grade aluminum (60 × 25.4 × 11mm, 24g) with 0.96-inch IPS display. Dual PCB layers separate digital and analog circuits—borrowed from flagship RU6/RU7 models. Available in Black, Light Cyan, and Purple.
