Cayin N7+ 1-bit DSD Digital Audio Player

Power Boost
The optimized headphone amplifier architecture delivers a significant boost in output power—up to 330mW (+32%) from the 3.5mm PoE and 690mW (+38%) from the 4.4mm PoE—making it effortlessly compatible with everything from high-sensitivity IEMs to high-impedance headphones. This upgrade ensures richer detail and greater dynamic control across a wide range of listening gear.

Enhancing the design further, the four power transistors have been upgraded to PHPT610030NPK models, improving transient current handling. Additionally, the seven OPA1612A op-amp ICs now use a SOIC-8 package, offering significantly better thermal stability. The improved pin layout and electrical characteristics reduce latency and crosstalk, resulting in cleaner signal transmission and purer audio reproduction.

Fully Discrete and Fully Balanced Portable Audio
A groundbreaking product in the portable audio market, the N7's DAC is constructed from 128 discrete resistors, with 32 resistors per channel across four channels forming a fully differential balanced structure. This truly demonstrates a 1-bit circuit architecture comprised of fully differential discrete components.

Discrete components are used throughout the LPF closed-loop gain, negative feedback level, and circuit architecture, ensuring high-performance overall circuit amplification. The AMP utilizes audio-specific field-effect transistors (JFETs) for the differential input stage, and paired-package transistors for the voltage amplifier and power output stages, resulting in low internal resistance and strong load-driving capability.

Sound Foundation
The power system, combined with 1-bit circuitry, provides completely independent power supply for the digital and analog circuits. Within the digital circuitry, high-level and low-level logic circuits are also completely independent, ensuring that the transmission and amplification process is free from interference from clock signals, resulting in a cleaner audio signal

Fast and Smooth System
Powered by a Qualcomm Snapdragon 665 octa-core 64-bit processor, this device combines 4GB of RAM with 64GB of internal storage, plus support for up to 1TB via TF card expansion. Running on Android 12 with DTA lossless output support, it ensures high-quality audio performance across Android devices.

Dual-band 2.4GHz/5GHz Wi-Fi is enabled by a specially designed metal-frame antenna, delivering strong signal strength and reduced interference for fast, stable streaming. It also supports OTA firmware updates and app installations for a customizable and future-ready experience.

Long-Lasting Battery
The N7+ features an optimized internal power system design. In PoE mode (Class AB), a single-ended battery life of 3.5" allows for up to 13 hours of full-day music playback, ensuring you never have to worry about running out of power. It supports PD2.0 fast charging.

Upgraded Look and Feel
The N7+ has been comprehensively upgraded in both appearance and craftsmanship. The new titanium-colored housing is crafted from aircraft-grade aluminum-magnesium alloy using a CNC process, balancing lightweight design with high-strength protection. It visually displays a delicate metallic luster, ensuring "at first sight, at first grip, you'll fall in love."
