Cayin HA-6A

  • Versatile & adaptable high-end tube headphone amplifier with EL34 tubes (also compatible with KT88 tubes)
  • Powerful and adaptable high-end headphone amplifier.
  • Allows a differentiated sound tuning by the possibility to replace the included EL34 tubes with KT88 and the operation in triode or ultralinear mode.
  • Perfect impedance matching to the respective headphones.
  • Manual wiring of the audio circuit.
  • Voltage rectification via tubes.
  • Perfectly selected output transformers for unrivalled quality of the balanced output with impressive spatiality, channel separation and dynamics.
  • Purist power management: The multi-stage, separate voltage amplification of the power supply with independent voltage regulation minimises the ripple effect caused by current interference. This ensures musical and smooth playback without graininess and harshness.
  • High-precision audio potentiometer with 24-step control via resistors selected in pairs.
  • Cable construction using silver-plated audio cables with excellent shielding to prevent interference.
