SERIES: MHA100 Headphone Amplifier
TYPE: Lifestyle

The new MHA100 is the first dedicated headphone amplifier from McIntosh and employs a new adaptation of our Autoformer technology to produce three headphone impedance ranges of 8-40, 40-150 and 150-600 ohms so every headphone will produce the best possible personal listening experience. Features our new Headphone Crossfeed Director (HXD) to allow high quality recordings to image like conventional speakers in your headphones.



  • Four digital inputs allow the McIntosh Digital Engine to decode your digital music at up to 32 bits and 192kHz for maximum analog fidelity and enjoyment.
  • Smaller, more compact size than other McIntosh amplifiers allows additional flexibility in locating the MHA100 in your space.
  • Includes 50 watt speaker output for when you want to enjoy your favorite speakers instead of your headphones, along with 5 Step Bass Boost Control for further customization.
