CHORD MOJO and Android phone source provided, and fantastic collaboration between our JUNE ACOUSTICS headphone amplifier and HD800S

Design Concept

It is a flagship model of aluminum barrel cutting.

Configuration of whole circuit (conceptual diagram)

 The basic configuration is the same whether it is a headphone amplifier or an amplifier that drives speakers. In addition, the method of driving the dynamic speaker is divided into a current type and a voltage type. It has a damping control VR that determines the ratio of the current output to the voltage output so that it does not hit the flagship model and the VR that adjusts the impedance of the headphone.


    • Maximum output 300Ω 2W THD 1.5% or less
    • Input open VR MAX Noise = 0.3 mv or less
    • CCITT Weighting = 0.04mv or less
    • S/N RATIO = 114dB
    • Size = (WHD) 300 x 65 x 220
    • Weight = 6Kg
