Cayin N7, the new portable Digital Audio Player (DAP) from the leading audio manufacturer will make its worldwide debut at CanJam New York 2023. Cayin surprised portable audiophiles with their unique fully-balanced fully-discrete vacuum tube amplified DAP back in CanJam New York last year. The N8ii becomes a reference immediately and remains one of the most discussed DAPs today. The N7 takes a completely different direction by developing the first miniature pure 1-bit DAC circuit with a four rail resistor network. This is probably the closest proximity to an analogue experience in any current DAP application. The discrete 1-bit DAC can native decode up to DSD512 and accept PCM up to 32 Bit/768kHz. Cayin also developed a discrete LPF (low pass filters) circuit to tune the output stage of their 1-bit DAC to closely resemble the smooth and natural sound signature we have in mind. The headphone amplification of N7 is nothing short from spectacular; it is fully-discrete, fully-balanced design with a renowned Dual Amplifier Operation (DAO, choice of Class A or Class AB) feature. N7 is Android 12 based with Google play preinstalled so it is streaming ready.

Fully-Discrete Design

Cayin N7 is the world’s first portable audio player that features a fully-discrete audio circuitry in a fully balanced design. Going discrete is technically more demanding but it allows more room to fine-tune the sound signature and deliver superior performance over Op-AMP-based regular circuit design. With its fully-discrete circuitry, Cayin N7 minimizes interference and maintains a clean, pure sound output.

Pure 1-Bit DSD DAC

Cayin has designed a fully-discrete 1-Bit DSD DAC that converts the digital signal to analog through a resistor network series composed of 128 high-precision thin-film resistors. A precisely implemented FPGA enhances the digital audio signal and outputs L+, L-, R+, R- digital bitstream to fully balanced decoding. DSD signals are passed through unaltered, and PCM signals are converted to a 1-Bit bitstream before it is transmitted to the DAC circuitry. Pure 1-Bit DSD DAC promises a pure, natural, rich sound decoding greatly enhancing the output sound listening experience.

Discrete Headphone Amp Circuit With Class A/AB Dual Operational Modes

Cayin N7 features a 4-channel discrete component-based fully balanced headphone amplification circuitry. It adopts low-noise audio grade JFET(Junction Gate Field-Effect Transistors) as differential input stage and BJT(Bipolar Junction Transistor) as the voltage amplification and output stage. Cayin N7 features Class A and Class AB easily selectable dual-operational modes for the amp circuit. It delivers the high-power low-noise output with special optimization for low-impedance high-sensitivity IEMs. Class A amplification requires all channels to be in near-identical gain, they are manually matched and manually installed to the PCB before final soldering.

Independent Ports for Headphone Output and Line-Out

Cayin N7 features 3.5mm and 4.4mm output ports. It has independent ports for headphone output and line-out/pre-out. Apart from the 3.5mm/4.4mm, Cayin N7 also supports I2s, USB, and Coaxial digital output options. It is widely compatible in different desktop and portable scenarios.

Precise JRC Electronic Volume Control

Cayin N7 features a low-noise, low-distortion electronic resistance ladder-based volume control from JRC. The controller uses a 4-channel in one integrated controller chip that offers precise Volume adjustments and lower power consumption.

True High-Resolution Portable Audio Player

Cayin N7 is a pure flagship-grade digital audio player that supports all-leading audio formats. It supports high-resolution 32-bit/768kHz PCM signals along with native DSD512 audio signals. It also supports full 16x MQA unfolding. Cayin N7 also has high-resolution two-way Bluetooth connectivity with class-leading LDAC, UAT, AAC, and SBC transmission protocols.

The Perfect Portable Media Player

In order to pack a smooth user interface, Cayin has featured Qualcomm’s highly-trusted Snapdragon 665 SoC chipset with 4GB of RAM and 64 GB of internal storage. The player features an open Android 12 OS that opens the doors to an unlimited number of media applications. It supports systemwide high-resolution decoding with SRC bypass.

Long Playback Duration With Fast Charging

Cayin N7 houses a large 9000mAh battery pack that provides a battery back of anywhere between 6 to 10 hours. It supports PD2.0 quick charging that charges the DAP from 20% to 80% in just 2 hours.
