New and Improved
The Cayin N6iii boasts a 5” all-screen display, larger than the N6ii’s 4.2” but still compact and ergonomic for one-handed use. By eliminating chassis extensions and neatly placing playback buttons and the volume knob under the screen, the N6iii balances enhanced visuals with portability.
Curved sides improve grip, ensuring comfort despite the larger display, while maintaining the device’s portability and sleek design.
For improved streaming, the N6iii uses a semi-exposed antenna below the top panel, offering better performance than the N6ii. Though it provides slightly less gain than external antennas on models like the N7 or N8ii, this design enhances connectivity without increasing size.

Replaceable Audio Motherboard
The N6iii introduces a quick-release 3-point locking system for easy, tool-free audio motherboard swaps, inspired by the C9ii. Its Gen2 Audio Motherboard, featuring Cayin’s latest audio technologies, is larger for enhanced performance but not backward-compatible with N6ii boards, balancing innovation with portability. Each motherboard tailors the N6iii to unique listening preferences.
C201, E203 and R202 Audio Motherboards


The C201, E203 and R202 motherboards for the Cayin N6iii differ in design and sound performance. The C201 features 8x Cirrus Logic CS43198 DAC chips, delivering a clean and transparent playback with a slight smoothness to the highs.
The E203 uses dual ESS ES9038Q2M DAC chips, offering a more analytical, precise sound with enhanced clarity and dynamic range, catering to those seeking a highly detailed and neutral listening experience.
The R202 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. While R-2R Mode provides a rich, smooth sound, 1-Bit Mode offers a more natural rendering with a clear soundstage.
C201
The C201 is the first time Cayin has used a Cirrus Logic DAC chip in a portable product. Historically, in the early 2000s, the CS4398 and PCM1792 DAC chips were dominant in the audio industry, and Cayin used them extensively in its early DAC and CD players.

The C201 audio motherboard in the N6iii features (x8) Cirrus Logic CS43198 DAC chips, arranged in a “Parallel Full-Differential Matrix DAC” design. Each DAC operates in MONO mode, receiving individual I2S signals and outputting differential signals. Groups of (x4) DACs combine for a full-differential output channel, with discrete, symmetrical power supplies ensuring stability and precise phase alignment. This low-jitter, high-performance design enhances sound density, reduces distortion, and delivers exceptional audio quality.

E203
The DAC chip in the E203, the ES9039SPRO, was developed under the latest Hyperstream® IV architecture.
The ES9039SPRO features an 8-channel independent current output path, to align with this design, Cayin has implemented an 8-channel independent I/V (Current-to-Voltage) conversion circuit corresponding. It is followed by the LPF circuit to extract four fully-differential signals, which are then paired with a Buffer driver circuit.

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.
