The Cayin CP6 features a matched pair of Raytheon JAN6418 military-grade NOS tubes in a dual-channel Class A amplification circuit. PO, LO, and Bluetooth outputs all support one-touch switching between three timbres.

A dedicated 22V low-noise power supply and DC filament design minimize noise and hum while preserving resolution, delivering a warm, transparent, and refined tube timbre.

Optimized JAN6418 tube circuitry delivers two distinct tube timbres. Switch freely between Classic Tube Timbre, Modern Tube Timbre, and Solid-State Timbre to match different headphones and listening preferences.

• Classic Tube Timbre — Warm, smooth, and vocal-rich.
• Modern Tube Timbre — Spacious, detailed, and dynamic.
• Solid-State Timbre — Clean, neutral, and transparent.

Switch between external DC power and the built-in battery. Enjoy up to 7.5 hours of playback on battery power, with support for QC/PD fast charging.

In DC Mode, the optimized amplifier power supply boosts output power to 1300mW. Ultra-low standby power consumption also helps preserve battery life during long-term storage.

Switch between Class A and Class AB operation to suit different music genres and listening preferences.

1300mW + 1300mW (16Ω) | 1100mW + 1100mW (32Ω)

• Class A Mode — Warmer timbre, smoother presentation, and lower distortion.
• Class AB Mode — Higher efficiency, stronger dynamics, and greater output capability.

Powered by the Qualcomm QCC3083 high-resolution Bluetooth solution, the CP6 integrates both Tx (transmit) and Rx (receive) modes in a single design.

Bluetooth 5.4 ensures more stable connections, stronger anti-interference performance, lower latency, and wider codec coverage for high-resolution wireless audio.

With Bluetooth timbre support, wireless listening still delivers a rich and engaging sonic character.

• Bluetooth RX (Receiver Mode): SBC / AAC / aptX / aptX HD / aptX Adaptive / LDAC
• Bluetooth TX (Transmitter Mode): SBC / aptX / aptX HD / aptX Adaptive — supports direct connection to wireless headphones and Bluetooth speakers.

The CP6 works with the Cayin Control App for deep customization. Intuitive operation makes everyday use more seamless and tailored to personal preferences. Future firmware updates will continue expanding features and functionality.

The amplifier adopts a voltage amplification + high-power transistor push-pull current stage architecture, delivering stronger current drive and precise control. It is capable of driving 8Ω–600Ω headphones, while maintaining ample current headroom even with low-impedance loads such as 8Ω and 16Ω.

• Voltage Amplification Stage: Uses dual TI OPA1652 audio op-amps. High slew rate, low distortion, and excellent transparency, providing a clean and stable signal foundation with strong control for the next stage.
• Power Output Stage: Employs four Nexperia PHPT610030NPKX high-power transistor pairs in a push-pull current amplification design. Delivers high current output and low output impedance, ensuring strong driving force, full low-frequency response, and solid dynamics.

Equipped with a custom anti-shock CD mechanism, precision laser pickup, and a professional servo system, the CP6 uses a high-end hardware architecture for stable and efficient disc reading.

Strong error correction ensures faithful reproduction of the original CD sound quality with fine detail.

Supports lossless CD ripping, allowing CDs to be digitally archived to the device in lossless format. This preserves classic music collections while meeting both daily playback and digital library needs.

Supports FAT32 storage devices only.

• Physical damping system: Custom JAN6418 damping sleeve, shielding cover, and chassis suspension structure work together for multi-directional shock absorption.
• Circuit stability design: Interstage feedback with local negative feedback reduces closed-loop gain and stabilizes multi-stage tube power supply, ensuring steady filament current.
• Combined structural and circuit optimization effectively suppresses microphonic effects.

Built-in 16-core XMOS XU316 USB audio platform serves as the core of the device's digital input stage, supporting both UAC 2.0 / UAC 1.0 modes for wide compatibility.

Compatible with Windows / macOS / Android / Linux, offering driver-free plug-and-play operation across major systems.

Adopts an asynchronous transmission architecture with a high-precision clock system to reduce jitter and isolate computer-side noise. This ensures a stable, clean digital signal stream for the downstream DAC stage, delivering a low-noise, high-purity Hi-Fi foundation.

The CP6 adopts dual Cirrus Logic CS4308P 32-bit / 8-channel high-performance DACs, operating in mono mode to achieve fully parallel differential current output.

Paired with dual OPA1612 I/V conversion and low-pass filtering stages, the circuit delivers ultra-low distortion, low noise, and high linearity, ensuring accurate retrieval of micro-details and dynamics.

Independent left/right channel operation enhances channel separation and expands soundstage precision, resulting in a darker background and more stable imaging.

• Battery & Charging System: Supports DC / BAT dual power modes, equipped with a 7300mAh 3.85V high-voltage Li-ion battery, delivering up to 7.5 hours of playback. Powered by TI BQ25895 charging management IC, with intelligent thermal control, supporting charge-and-play operation for greater flexibility.
• Multi-Stage Precision Power Architecture: The power stage combines dual LT8334 controllers with TLV61046, TLV62568, and TPS61087 to form a high-efficiency DC-DC power supply with low heat generation and high current capability. Fifteen LP5907 ultra-low-noise LDO regulators, together with multi-stage filtering, effectively suppress voltage ripple and power supply noise, delivering an exceptionally dark background and a cleaner listening experience.

A JRC NJW1195A 4-channel electronic volume controller enables fully balanced volume control with 0.5dB adjustment steps, delivering excellent channel separation, click-free operation, and transparent sound.

Signal switching is handled by the onsemi FSA2275 audio switch, featuring low on-resistance, low THD+N, and pop-noise suppression for clean, lossless signal switching.

CD Player, Digital Transport, USB DAC, and Bluetooth Transceiver — all in one.

• Input — CD / USB / Bluetooth
• Headphone Output — 3.5mm Single-Ended + 4.4mm Balanced / Dual Gain
