Innovation Power Supply Design
– With DAC Decode
– USB intelligent Charging
– By internal NX2 it’s a 1000mAh large-capacity litchium polymer battery which the battery life can reach max 100 hours.
– 220V working voltage can give full play to the op-amp and guarantee the good performance. NX-1 is able to drive high impedance headphones which enough dynamic level range
– NX-2 can adapt to the charge output of computer USB port and varitey of plugs. It automatically adjust the suitable charging current with the fastest speed to supplement the battery. Only need 1 hour if charging via 2A supply.
Details define quality
– Humanized function Indicators

Classical Designed Circuit
Op-amp circuit still adopted the mature classic op-amp + buffer design
Has achieved in the best balance between high quality and reliable lasting dyrability, which is equipped with a selection of high quality audio devices such as WIMA capacitance, ALPS potentimeters.
The part of the power supply adopts high frequency low resistance capacitance with is very low loss and resistance.
The voice is as brilliant as steinway piano which is with 50 years history
