Product Details


MX3 use OP+BUF headphone amp to provide 257mW(32ohm) output power,which is 190% of VX3.Beside,MX3's built-in headphone amp provide 0.006%THD+N,and 20-200KHz frequency response.

Exquisite aluminum case
We designed MX3's case by arcs and lines and combined with the design of hidden screws,which make no screws on front panle and around.In order to have a better surface,we use same surface with MAC BOOK.

Auto On/Off function for all digital inputs except AUX

MX3 could serve as a Bluetooth receiver.Close to the MX3's NFC label to fast connect MX3's Bluetooth input and enjoy Bluetooth music.If your phone or tablet dones not has NFC,you can search Bluetooth to connect.Close to the NFC label again to disconnect Bluetooth.You can connect output signal from headphone out.


4.Amplifier for disc player&digital player
You can connect the cozxial/optical output of your disc player/digital player to MX3.Then you can enjoy music without buting a DAC.


5.Simple power amp&headphone amp
MX3 could also serve as a simple power amp%headphone amp.Input signal could be player,dac,TV,phone,PC and etc.


If you want to use other amplifier,MX3 COULD SERVE AS dac+Pre-amplifier.Connect input signal to BT/USB/Optical/Coaxial/AUX,then connect output signal from headphone output.


7.Simple Pre-amplifier
If your system already has amplifier and DAC,MX3 could serve as a simple pre-amplifier.

  • Taimoor 4/28/19 11:29 AM Asked.
  • Q: Could I use the headphone out to feed 2 powered monitors to take advantage of the 20Hz-200kHz frequency response? My monitors have 42Hz - 50kHz frequency response.
  • A: Hi,YES, you can.Thank you!
  • Paul Hammond 10/23/18 8:30 AM Asked.
  • Q: Frequency response listed here must be a typo. 200kHz ? Surely it is 20Hz to 20kHz same as all other Topping Dacs?
  • A: Hi, Thanks for your message.The Headphone output frequency response is 20Hz-200KHz(±0.1dB).The speaker output frequency response is 20Hz-20KHz(±0.8dB). Thank you!
