Newly developed NFCA Module:
Topping developed a new NFCA Module specially designed for portable amplifiers. NFCA (Nested Feedback Composite Amplifier) module enables it to produce clean and high power at a very low output impedance. The NX7 has an astonishing 0.00007% THD+N and 135dB SNR rating.
Suitable for both Sensitive IEMs and power-hungry full-sized headphones:
With three adjustable gain levels and low output impedance, it can drive both IEMs and full-sized headphones to their full capability.
It can output 180mW/300ohms. Moreover, with the help of three adjustable gain levels, it becomes even more versatile. The distortion is very low at 0.00008% even with 200mW output.
Impressive performance with IEMs:
With -13.8dB on low gain, you can use it with your highly sensitive IEMs with ease with precise volume control.
Low output Impedance:
It has a <0.1 output impedance. As a result, there is no coloration with highly sensitive IEMs. With Topping NX7, you can forget about sound matching and use it without any hiss.
20h battery life:
The NX7 is optimized for long battery life. Even with the medium gain, you can get 20 hours of battery life, while the battery life still reaches 10h with high gain.
Anti-Mistouch and anti-breaking design:
It has corner guards to prevent accidental volume change, which also helps reduce the possibility of breaking the headphone plug.
