TOPPING NX4 DSD High performance headphone amplifier with integrated USB DAC.

Simple and effective

The Topping NX4 is the ideal solution, easy to use and extremely effective, to give your headphones a whole new dimension. It pushes the limits by exceeding the specifications required for hi-res high resolution files with a bandwidth of 20Hz - 100kHz.

Highest quality components

The NX4 DSD incorporates market references in terms of components, designed to offer optimum Hi-Res certified performance. The high-quality circuit incorporates an XMOS U208 USB interface with three separate clocks, an ES9038Q2M DAC and the latest generation TI OPA2140 operational amplifiers. This architecture allows it to support PCm sample rates up to 32-bit 768kHz and DSD512 up to native DSD. Furthermore, it provides an SNR of 119 dB and a THD + N of only 0.0008% in USB DAC mode.

An autonomy suitable for multiple uses

The Topping NX4 DSD incorporates a considerable battery that allows it to have extended autonomy for long listening sessions, whether on the move with a smartphone or in sedentary mode using the DAC function. Therefore, its autonomy is 28 hours in reading mode in headphone amplifier mode and 7:30 in USB DAC + headphone amplifier mode. LED indicators let you know when the NX4 DSD needs to be charged.
