Topping NX3s

Portable Headphone Amplifier on Battery Hi-Res OPA2140 + LME49720

Topping NX3s Amplificateur Casque Portable sur Batterie Hi-Res OPA2140 + LME49720

The NX3s Topping is a portable, battery-powered headphone amplifier that is ideal for enjoying improved sound at home or on the go. The device offers a high quality design, using only high-performance components.

Beyond Hi-Res audio

NX3s benefits from Japanese Hi-Res certification, which guarantees superior sound quality. For this purpose, the amplifier is able to reproduce a frequency range from 20Hz to 200kHz, ensuring an impressive level of detail, far from a CD quality (20Hz-20kHz) or standard Hi-Res (20Hz-40kHz).

Comfortable output power

Portable Headphone Amplifier on Battery Hi-Res OPA2140 + LME49720 Capable of delivering a power of 2x545mW under 300Ω (THD+N <1%) or 2x100mW under 32Ω (THD+N <1%), the NX3s is able to support a large majority of headsets on the market.

Excellent performance

The overall performance of the amplifier is excellent, with a THD+N of less than 0.0017% at 1kHz, for an output of 273mW at 300Ω or less than 0.0003% at 1kHz for an output of 50mW at 32Ω The noise level is less than 2.5µVrms with the gain set to "low" or less than 6.5µVrms with a gain set to "high". Finally, the SNR is higher than 120dB. These measures ensure a precise, rich and clean restitution.

Interchangeable OPA

The NX3s features an OPA2140 and a LME49720 OPA to provide a highly musical reproduction. The LME49720 OPA is installed on a DIP8 bracket, allowing it to be easily changed to a different model and thus adapt the sound to its listening and system.

Consistent autonomy

With a 2400mAh Li-Ion battery, the NX3s is able to play your music for no less than 18 hours, before requiring a new charge. The amplifier can be charged via Micro USB in 0.5A or 1A. Using an AC adapter that provides 1A of power, the full charge takes only 4 hours!

Bass Boost & Gain Setting

The NX3s Topping offers a Bass Boost mode (can be activated or not) to increase the reproduction of low frequencies for a lower sound or a gain setting between 0dB (Low) and 8.8dB (High). This last setting allows it to adapt to more than one source.

Easy to use

The design of the NX3s has been designed to be truly portable so that it can be carried everywhere. Thus, it fits easily in the hand or in a pocket. In addition, the design of the volume knob has been designed to limit unwanted sound level adjustments. The unit is extremely simple to use with a simple input and output, as well as a charging connector.

High quality components

All the circuits include high quality components, which are at the heart of the NX3s' sound quality. These are only HiFi components such as an ALPS potentiometer or WIMA capacitors.
