Topping A30 - Desktop Amplifier (New Model)



- Two outputs for different impedance of the headphone: 3.5MM and 6.35MM headphone port, can be used for a variety of headphones and earbuds.

- Two kinds of operating voltage mode and three kinds of gain (0dB / 9dB /18dB) selection mode.

- A30 uses the high-performance TI HIFI chip OPA161, OPA2134 (changeable) and TPA6120.

- Maximum output power of A30 can reach up to 1551mW * 2.

- Aluminum body, each part is through high automation, high-precision machining creating (Laser engraving).

- Power by a special customized three-way high-performance linear power supply

Most competing products use 1x15V or etc adapter to the amplifier, this 1x15V will be convert inside the amplifier and cause noise and interference. But we use linear power adapter to provide 2x15V and 1x8V to A30, which help A30 avoid these problem. 2x15V used for high fidelity headphone amplifier circuit. 1x8V used for MCU, LED and relay. Less noise, less interference.

- Using Hi-fi grade NEC relay, WIMA capacitance, Nichicon FW series HIFI electrolytic capacitor, ALPS potentiometer etc

Topping NX1


Topping NX1A (new model)



The 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.


NX1A keep same circuit and component of NX1 to keep a same sound. But after modifying other part to save power, NX1A’s playback time up to 150h, that’s 50% improvement of NX1. It takes less than 3 hour to fully charge the battery. Even 5 minutes charge could provide 10 hour playback.

Its USB charging port has been enhance to be able to use standard Micro Usb cable for charging

  • 100mW*2 output power.
  • Built-in rechargeable lithium battery, approx 150 hours playback time.
  • Selectable gain (H & L)
