AUNE B1 Class A Hi-Fi Audiophile Portable Headphone Amplifier (2017 Version)


  • B1 2017 version: Line optimized for high sensitivity earphone gain
  • Aune team create a fully separated class A portable headphone amplifier for reproducing high sound quality
  • Using a linear fully discrete amplifier, Class A output bias, adjustable gain and output current control, aune successfully applied the excellent all-discrete Class A technology to portable amp
  • HIFI portable player and HIFI phone ideal sound quality upgrade peripherals
  • HIFI portable player can not make the internal headphone amplifier very excellent because the size and volume; B1 is a portable pure HIFI headphone amplifier, connected to the portable audio player output to enhance the sound quality of the player
  • B1 Regeneration warm and soft sound
  • B1 can be easily connected to the HIFI player and high-quality phone LINE OUT port, the use of a special type of even-order harmonic characteristics, renewable warm mellow and soft tone
  • Regenerate a greater driving force and headphone adaptation range
  • B1 control switch through the gain switch and current , driving the market most of the headphones and earplugs, connected to your player can expand greater headphones ranges , including HD650, DT990 and SE535, IE80 and other headphones are compatible.
  • B1 uses the whole discrete transistor to form the main amplifier circuit
  • Fully Discrete Components: Amplifiers are designed for fully discrete components. Fully discrete three-level amplifiers have large change rates and transients. The fully discrete component amplifiers feature is having extremely wide frequency response and is characterized by an extremely high frequency extension and rapid low-frequency, at the same time with the level of clear mids.
  • B1 output stage using Class A amplifier bias design

  • B1 output stage using Class A amplifier bias design, in the 32ohm headphones to provide 4OMW  Class A power, A class characteristics makes the B1 amplifier excellent high-frequency extension and rapid low-frequency and level of clear midrange in discrete and amplifier , With a warm mellow sound, very close sense!
