Cayin CP6 is a portable CD player that combines disc playback, USB-DAC, bidirectional Bluetooth and headphone amplification in a single device. The design combines two Raytheon JAN6418 NOS valves, a digital section based on dual Cirrus Logic CS4308P DACs and a fully balanced, discrete headphone amplifier. The result is a source designed for those who want to use their CD collection on the move, connect different headphones or integrate the player into a larger audio system.

CD playback and digital functions

The CP6 keeps CD playback at its core, while adding several digital usage options. The proprietary Anti-Shock CD mechanism is designed for reading discs in a portable device. In addition to direct listening, the player enables lossless CD ripping to USB storage, allowing the contents of your discs to be transferred to an external medium.

The device can also function as a USB-DAC. The USB platform uses the XMOS XU316 processor, with Plug-and-Play support indicated by the available data. This allows the CP6 to be used as a conversion and listening component for a source connected via USB, as well as an independent CD player.

Digital conversion is handled by a configuration with two Cirrus Logic CS4308P DACs. This architecture works alongside the analogue section and balanced amplifier, providing a common foundation for the different sources managed by the player: CD, USB and Bluetooth.

Valves and triple sound signature

One of the distinctive features of the Cayin CP6 is the use of two Raytheon JAN6418 NOS valves. The valve section allows you to choose between three sound modes, called Classic Tube, Modern Tube and Solid-State. The change can be made using a dedicated control and does not apply only to the headphone output: all three settings are also available for the Line-Out and Bluetooth output.

This configuration makes it possible to adapt the player’s operation to the type of connection being used. Solid-State mode excludes the character of the valves in the profile name itself, while the two Tube modes use the Raytheon JAN6418 valves according to the respective configurations specified by the product. The available data therefore describes the CP6 as a device with a triple sound signature, capable of offering three selectable options without changing the source or headphones.

Balanced headphone amplifier

The headphone amplification circuit is fully balanced, discrete and arranged across four channels. Class A or Class AB operation can be selected, allowing one of the two operating modes provided by the design to be chosen. The CP6 features both a 3.5 mm output and a 4.4 mm balanced output.

The declared compatibility covers headphones with an impedance between 8 and 600 ohms. This range includes both low-impedance models and high-impedance headphones, according to the characteristics specified for the device. In DC power mode, the balanced output can reach up to 1300 mW + 1300 mW at 16 ohms. This value refers to the balanced configuration and external DC power; it should therefore not be interpreted as identical power in every operating mode or with every headphone.

The 3.5 mm and 4.4 mm connections can also be used as Line-Out outputs. The player therefore offers flexible management both for personal headphone listening and for connection to an external audio system.

Bluetooth transmission and reception

The CP6 integrates Bluetooth 5.4 and the Qualcomm QCC3083 chipset. Bluetooth is bidirectional: the player can receive a signal from a compatible source or transmit audio to a Bluetooth device. Supported codecs include LDAC, aptX Adaptive and aptX HD.

The transmission function expands the player’s possible uses, because audio from CD, USB or other sources managed by the CP6 can be sent to a compatible Bluetooth device. The triple sound signature is also available for the Bluetooth output, according to the information provided. For wired listening, the 3.5 and 4.4 mm headphone and Line-Out outputs remain available.

Connections and outputs

The player is designed to work with multiple sources and different types of connected equipment. The indicated inputs are CD, USB and Bluetooth. On the output side, in addition to the analogue connections, three digital outputs are available:

• coaxial output;
• optical output;
• Bluetooth Transmitter, for wireless transmission.

This equipment allows the CP6 to be used as an independent player with headphones, as a source for a system via Line-Out or as a digital transport to devices equipped with a coaxial or optical input. The actual availability of functions depends on the type of connection selected and the connected device, while Bluetooth can operate as an input or output thanks to its bidirectional nature.

Battery life and power supply

The Cayin CP6 can operate using its integrated battery or an external DC power supply. The battery is a Lithium-Polymer type, with a stated capacity of 7300 mAh and 28 Wh. Battery life reaches up to 7.5 hours, depending on the operating mode used. This figure refers to the operating conditions specified by the manufacturer and may vary according to the source, output, volume and selected mode.

To reduce waiting times, the player supports QC3.0 / PD2.0 fast charging. The stated fast-charging time is approximately 2.5 hours. DC power also makes it possible to use the CP6 in a more stable context, such as a fixed setup, and enables the maximum stated value for the balanced output.

Display, construction and control

The device’s functions are managed through a 2.3-inch colour display. The screen supports source selection, sound mode selection and the settings available in the player’s interface. Support for the Cayin Control App for device control is also indicated.

The chassis is made of aluminium, with CNC machining indicated in the product description. The metal construction and portable format complete a design intended for use both away from the system and in a home configuration. The stated weight is 0.7000 kg. Overall, the CP6 combines a CD player, DAC, headphone amplifier, ripping functions and Bluetooth connectivity in a single device, while retaining analogue and digital outputs to adapt to different listening systems.
