Cayin R202 Audio Motherboard for N6iii

Transform Your DAP, Instantly — The R202 is a modular audio motherboard for the Cayin N6iii, fully replacing both DAC and analog sections. Featuring a discrete R-2R and 1-Bit DAC architecture, quad-channel balanced amplification, and smart decoding modes, the R202 redefines flexibility and sonic excellence in portable audio.

Key Highlights

  • Modular Design: Quick-release latch mechanism allows instant motherboard swaps with no tools required.
  • Dual DAC System: Fully discrete R-2R DAC for PCM and discrete 1-Bit DAC for DSD with native decoding.
  • Smart Mode Switching: Auto mode selects R-2R for PCM and 1-Bit for DSD formats seamlessly.
  • Quad-Channel Balanced Amplifier: Built with OPA1612, OPA1662, and INA1620 op-amps for pure differential amplification.
  • Precision Volume Control: NJW1195 256-step analog controller with 0.5dB resolution per channel.
  • Clean Power Design: LT8582 boost supply and 7 ultra-low noise LDOs for clean, isolated digital and analog power.
  • Balanced Output Only: Designed exclusively for PO use — no LO output — for pure signal path integrity.

Three Listening Modes

  • Auto Mode: Automatically selects R-2R for PCM and 1-Bit for DSD for optimal decoding quality.
  • R-2R Mode: Smooth, rich, and analog-like sound — ideal for relaxed, immersive sessions.
  • 1-Bit Mode: Sharp, pinpoint imaging and clarity — especially effective with acoustic and classical genres.

Engineering Excellence

Both DACs use ultra-high precision 0.1% thin-film resistors: 192 for the R-2R DAC, and 128 for the 1-Bit DAC. Paired with low TCR characteristics (<5ppm/°C), this ensures waveform accuracy, low harmonic distortion, and high dynamic range.

The quad-channel balanced amplifier is powered via matrix-isolated supplies with dedicated power paths for DAC, op-amps, and clocks. This attention to detail reduces noise and interference dramatically.
