Product Description
R202
The Cayin R202 motherboard is a high-performance audio module built around a fully discrete, fully balanced dual-DAC architecture. It features both a 24-bit R-2R ladder DAC and a discrete 1-bit DAC, each using ultra-precise 0.1% thin-film resistors for native PCM and DSD decoding. A dual digital audio processor supports up to PCM 768kHz and DSD512, with smart triple decoding modes—automatically selecting the best DAC architecture for the input format.
The motherboard also includes a quad-channel, fully balanced headphone amplifier built from high-grade op-amps and INA1620 drivers, delivering dynamic, transparent sound. Power is delivered through a matrix-structured clean supply with ultra-low-noise LDO regulators, ensuring a quiet, stable signal path.
