Cayin C9II
The Cayin C9II is a top-of-the-line (hi-end) portable headphone amplifier with many modern features and modifications, designed to satisfy even the most demanding audiophiles. Its standout features include three amplification modes (Class A, Class AB, and Hyper), adjustable anode voltage, and three selectable sound profiles: Solid State (transistor), Modern Tube (modern valve character), and Classic Tube (traditional valve character). The Cayin C9II excels with its robust construction, high-quality internal components, and precision craftsmanship. The dual NuTube design incorporates a pair of KORG Nutube 6P1 triodes—miniaturised valves that combine the classic “valve” sound with the advantages of semiconductor technology while maintaining maximum energy efficiency. The result is a warm, rich, and harmonically balanced sound that is very close to traditional triodes. Another advantage of the Cayin C9II is its discrete solid-state timbre circuit with Toshiba JFET transistors, which helps the amplifier achieve a precise and linear sound signature. The Cayin C9II amplifier is the ideal choice for users who appreciate high audio performance in a compact, elegant, and easily portable package.

Fully customisable sound delivery
The pair of miniaturised KORG Nutube 6P1 valve triodes, together with the JFET circuit from Toshiba, creates a hybrid design that can produce a wide spectrum of sound characters—from a smooth “valve” delivery to a precise and clean transistor sound. Thanks to the adjustable modes, you can fine-tune the sound to your exact taste or headphone type. The Cayin C9II offers three selectable tonal modes (Solid State, Modern Tube, Classic Tube), three amplification modes (Class A, Class AB, and Hyper), and an optional anode voltage that can be used for fine-tuning the sound. Additionally, the amplifier lets you switch the negative feedback (NFB) on or off, which affects the dynamics, warmth, and overall sound character.
Cayin C9II offers performance comparable to desktop amplifiers
Although it's a portable device, the Cayin C9II offers performance comparable to desktop amplifier models. Its wide frequency response from 11 to 80000Hz, along with a very low output impedance, ensures a clean and stable sound delivery without interference. The resulting music retains maximum detail, space, and liveliness, whether you're listening in the comfort of your home or on public transport. The amplifier is engineered to reliably drive and power even more demanding headphones, all while maintaining maximum control, dynamics, and sound clarity.
Battery power ensures maximum mobility
The Cayin C9II amplifier is powered by four replaceable, long-lasting Samsung 18650 rechargeable Li-ion batteries, which provide a direct current (DC) free from the noise and interference that can be transmitted from a mains socket. A key advantage is the fast charging via USB-C and convenient access to the batteries through an easy-to-open panel. Next to the USB connector are 4 LED indicators that show the remaining battery capacity and charging status. Thanks to its battery power, the Cayin C9II is the ideal choice for users who want to enjoy exceptional Hi-Fi performance anytime, anywhere.
Elegant design with easily accessible controls
The Cayin C9II amplifier has a robust aluminium chassis that is both durable and has a very elegant feel. Ergonomically placed controls provide convenient track switching, gain adjustment, operating mode selection, and anode voltage setting. On the underside of the device is a high-quality rotary volume control with gold trim. It also includes 3.5mm and 4.4mm inputs and outputs, ensuring universal connectivity with your music source and headphones. The overall craftsmanship and sonic versatility make the Cayin C9II a top-tier portable amplifier that will satisfy even the most demanding users.
