Topping NX1A (NX1 upgraded version) has been designed for MP3/MP4/mobile phone/computer that can not get best effect of high impedance from the headset due to the low power.

0.000015% Distortion
Splendid combination of Amplifier.
The topping NX1A use high performance chips, designed by TI CO,Ltd which is for audio.
Amplification and can bead to reach the extreme distortion degree index of 0.000015% almost zero distortion.

Classical designed circuit

Op-amp circuit still adopted the mature classic op-amp +buffer design.
The best balance between high quality and reliable lasting dyrability.
High frequency low resistance capacitance, very low loss and resistance
NX1A voice is as brilliant as Steinway piano which is with 50 years history.
