Cayin CP6 Triple Timbre Portable CD Player
Frequently Bought Together
Product Overview & Specifications
The Cayin CP6 is a flagship portable CD player, high-resolution USB DAC, and headphone amplifier that distills over two decades of Cayin's hybrid tube engineering into a mobile format. Built around a pair of US-made NOS (New Old Stock) Raytheon JAN6418 subminiature vacuum tubes, the CP6 features a proprietary anti-shock CD mechanism utilizing a multi-directional suspended chassis, tube-damping sleeves, and magnetic shielding to eliminate microphonic vibration. Driven by dual Cirrus Logic CS4308P DACs operating in mono differential mode and a 16-core XMOS XU316 USB platform, the CP6 delivers reference-grade desktop performance on the go.
Designed for extreme versatility, the CP6 supports Triple-Timbre selection (Classic Tube, Modern Tube, and Solid-State) across all phone outputs, line outputs, and wireless Bluetooth streams. Its four-channel fully discrete push-pull headphone stage operates in either Class A or Class AB bias modes, delivering up to 1300 mW + 1300 mW into 16 Ω under external DC power, or up to 7.5 hours of continuous playback via its internal 7500 mAh battery. Housed in a precision CNC-machined 6063 aerospace-grade aluminum chassis with a smoked optical glass CD viewing window, the CP6 bridges portable convenience with high-end Hi-Fi craftsmanship.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- NOS Raytheon JAN6418 Tube Architecture: Features hand-matched subminiature directly heated pentode tubes operating in a dual-channel Class A common-cathode topology with a 22V ultra-low-noise regulated power supply and DC filament design.
- Selectable Triple-Timbre Output: Instant switching between Classic Tube (rich and warm), Modern Tube (dynamic and open), and Solid-State (neutral and precise) sound signatures across all physical and wireless outputs.
- Dual Power Modes (DC & BAT): Operates via internal 7500 mAh lithium-polymer battery (up to 7.5 hours) or external DC power, which boosts voltage and bias current to output 1300 mW + 1300 mW @ 16 Ω.
- Proprietary Anti-Shock CD Mechanism: Custom optical mechanism featuring advanced error correction, suspension shock mounting, and lossless CD ripping directly to external USB storage.
- Dual Mono CS4308P DAC & XMOS XU316 Engine: Dual 32-bit Cirrus Logic DACs operating in full parallel differential mode, paired with twin OPA1612 I/V conversion stages and asynchronous USB audio processing.
- Fully Discrete Class A / Class AB Headphone Amplifier: High-power discrete push-pull output stage utilizing Nexperia PHPT610030NPKX transistors to comfortably drive headphones from 8 Ω to 600 Ω.
- Bi-Directional High-Def Bluetooth 5.4: Qualcomm QCC3083 wireless solution supporting LDAC, aptX Adaptive, aptX HD, AAC, and SBC in both transmit (Tx) and receive (Rx) modes with active tube timbres.
- Fully Balanced Precision Volume Control: JRC NJW1195A 4-channel electronic volume attenuator featuring 0.5 dB steps and an onsemi FSA2275 low-distortion analog switch network.
- Aerospace-Grade Aluminum Construction: Precision 6063 aluminum chassis with 180-grit sandblasted finish, Class 1 laser-safe smoked glass lid, 2.3-inch color display, and Cayin Control App integration.
