Cayin RU3 Black Hi-Fi DAC és ADC interfész

Portable Hi-Fi DAC with Desktop-Grade Power

The Cayin RU3 Black is a USB-C dongle DAC and headphone amplifier created to bring high-resolution audio to smartphones, laptops, and digital audio players. Compact dimensions belie the output power that rivals desktop amplifiers, so audiophiles can enjoy uncompromised sound on the go. This model merges advanced DAC circuitry and practical features, such as tactile on-device controls and deep app-based customization, all packed into a featherweight aluminum shell that slips easily into your pocket.

Dual-Core Architecture and Real Balanced Output

What stands out about the RU3 is its dual-core architecture based on the SPV5068 processor and ESS ES9069Q DAC. The result: genuine balanced output through dedicated amplifier stages, with clean, powerful sound and minimized noise that typically plagues single-ended designs. Employing Texas Instruments OPA1602 operational amps for current-to-voltage conversion and SGM8262 headphone amplifier chips, the signal chain remains pristine from input to output.

Technical Specifications for High-Resolution Audio

The RU3 is engineered to handle demanding digital audio formats while remaining adaptable for a wide range of headphones and listening situations.

• DAC Chipset: ESS ES9069Q — high-resolution dual-channel converter supporting PCM up to 32-bit/768kHz and native DSD512
• Balanced Output Power: 560 mW via 4.4mm connection provides ample headroom for planar magnetic and high-impedance headphones
• Single-ended output of 180 mW through the 3.5mm jack means conventional headphones and IEMs are also covered
• Processor: SPV5068 RISC-V dual-core for low-latency, energy-efficient USB transfer
• Dimensions: 60 × 25.4 × 11 mm make it compact enough to pair with any portable source
