TOPPING NX7
Portable headphone amplifier
The Topping NX7 is a compact and powerful portable amplifier that delivers accurate and detailed sound. It is equipped with a newly developed NFCA amplifier circuit specifically designed for portable amplifier systems. Its low power consumption allows long operating time while delivering excellent sound performance with 0.00007% distortion and 135 dB noise floor. It has the power to drive demanding headphones and sensitive earphones.
High performance in a compact size
The NX7 can deliver 2 x 180mW of power at 300Ω load impedance, with gain adjustable in three steps: -13.8dB, -0.1dB or +13.9dB, so you can easily cater for headphones with different impedances. Even at a high output power of 200 mW, it has extremely low distortion (0.00008%) and noise of less than 0.3 µV. With an output impedance of just 0.1 Ω, it provides colouration-free sound reproduction with headphones of all sensitivities.
Robust design and dual output
The NX7's components are mounted in a rugged aluminium housing for protection and worry-free portability. On the output side, the NX7 has symmetrical 4.4 mm and standard 3.5 mm Jack connectors, so it can be used with any listening device.
Optimized battery life
The NX7's optimized power usage results in high uptime, with up to 20 hours of continuous use at low and medium power levels, or 10 hours of continuous listening time in high gain mode with the built-in 4000 mAh battery.
