The brand new Cayin N8iii is a flagship digital audio player of reference level, designed for listeners who refuse to compromise on sound quality even on the go. Equipped with Nutube 6th generation tube circuit, flagship AKM DAC architecture, triple tone adjustment, and Hyper mode for maximum performance, the N8iii combines technical innovations, exquisite craftsmanship, and the unique musicality of Cayin.
Nutube 6P1 Tube Sound Scheme

Carefully selected dual triode tube with direct heating (DHT) Korg Nutube 6P1, manually matched for precision. The four-channel tube tone scheme provides rich and stable acoustic characteristics. Built on the classic three-stage Cayin amplifier scheme, it ensures optimal signal integrity and dynamic range.
- Classic Tube Tone: Represents a classic tube amplifier with relatively less thermal noise, but a richer, more lush sound;
- Modern Tube Tone: Harmonic distortion characteristics and sound character are more in keeping with modern styles, thanks to significantly reduced thermal noise and a cleaner tube sound;
- Transistor Circuit: Provides a neutral, transparent, and highly detailed sound.
Optimized Scheme and Layout

The tube tone scheme integrates a discrete JFET buffer cascade with constant current loading, improving linearity and dynamic range.
DFB Control

Accurate control of overall negative feedback depth allows precise tuning of the tube character, ensuring a smooth transition from classic warmth to modern clarity.
Vibration and Shielding

A four-layer protection system reduces microphone interference and absorbs random electromagnetic interference.
Beyond Class A

The N8iii features Class A+, Class A, and Class AB modes with instant switching. Easily adaptable to different sound characteristics and listening preferences. Class A+ mode enhances micro-detail playback and low-frequency resolution, with smoother dynamics, tighter bass control, and a more immersive soundstage.
Dual Voltage, Dual Output Power

Fully discrete amplifier cascades with switchable operating voltage. Switch between standard power (P) and high power (P+) modes. The high-power mode provides increased output power and improved control. The Hyper mode combines high power P+ and Class A+ amplification for maximum system performance, offering a wider soundstage and enhanced dynamic impact.
Fully Balanced 4-Channel Amplifier

Fully discrete 4-channel balanced amplifier built on a classic three-stage amplification architecture ensures precise channel separation and excellent signal integrity, providing better load control with different resistances.
Flagship DAC Architecture

The latest AKM flagship DAC solution for the N8iii includes (2x) AK4191EQ + (4x) AK4499EX. Fully discrete left/right channels create independent DAC systems for each channel. Working in monaural mode, the system provides fully parallel balanced current output, significantly improving dynamic characteristics and overall resolution.
Perfect Channel Matching

A special analog potentiometer paired with two high-quality electronic volume controllers enables fully balanced 4-channel hardware volume and amplification control with balanced signal transmission and amplification, ensuring superior linearity, low noise, and distortion.
Hyper Mode

A special headphone listening mode that activates both "High Power P+" and "Class A+" amplification, ensuring maximum system performance with a wider soundstage and increased dynamic impact.
Individual Power System

Designed to accommodate various loads and usage scenarios, the system provides pure and stable power from the source, with a 13500mAh lithium-polymer battery. Carefully selected power elements and high-precision low-resistance protection scheme ensure stable power delivery for demanding audio applications.
Advanced Cooling Control

Aluminum alloy 6063 body for improved heat dissipation, 8-layer high-performance PCB with gold immersion coating and 3D encapsulation layout reduce electromagnetic interference and increase system stability. Designed with high-Tg FR-4 (TG 2170°C) substrate using resin-filled via technology for strength, reliable current delivery, and optimized thermal characteristics.
Balanced Precision Volume Control

A special analog potentiometer paired with two high-quality electronic volume controllers allows precise 4-channel balanced hardware volume and amplification control with balanced signal transmission, ensuring excellent channel separation and accurate matching at low volume.
Direct Signal to DAC
Equipped with Qualcomm Snapdragon 665 octa-core 64-bit processor, 8GB RAM, and 256GB storage, as well as a high-performance FPGA for digital audio processing. Features DTA (Direct Transport Audio) architecture for high-quality playback. Supports up to 2TB TF card expansion, running a customized Android OS for seamless operation and extensive music storage.
Limited Edition. Only 500 pieces.
