Topping NX7

Portability + performance

The TOPPING NX7 is a portable amplifier with the features that count: incredibly low distortion, 20-hour battery life, and loads of output power.

NFCA amplifier

The new NFCA amplifier circuit was specifically designed for portable amplifiers. With a THD+N of 0.00007% and an SNR of 135dB, the NX7 is one of the cleanest portable amps on the market.

Drive full-sized headphones

The NX7 can output 180mW of high power under a load of 300Ω. With the help of its 3-step gain setting, it can easily power full-sized headphones. High power doesn’t equal high distortion. Even when the output is 200mW, the load distortion is only 0.00008%.

20-hour battery life

The NX7 can get up to 20 hours of battery life at low and medium gains, and 10 hours at high gain.
