The Power Your Headphones Deserve

The MHA150 Headphone Amplifier is a worthy successor to the critically-acclaimed MHA100. The MHA150 contains the same feature set and performance standards, but adds a new 2nd-generation digital-to-analog converter (DAC) that provides support for DSD and DXD files to give you access to the latest in digital music.

Main Features

  • Digital-to-analog converter (DAC) with support for DSD and DXD files to provide access to latest in digital music performance
  • Autoformer technology produces three headphone impedance ranges of 8-40, 40-150, and 150-600 ohms
  • Headphone Crossfeed Director adds natural-sounding dimension to music
  • Powerful and versatile enough to drive pair of desktop or bookshelf speakers

Prime McInTosh Technology

Like the MHA100, the MHA150 continues to take advantage of unique McIntosh technologies to create the best possible personal listening experience regardless of the headphones you use. The Autoformer technology found in McIntosh's large mono and stereo amplifiers has been adapted to produce three headphone impedance ranges of 8-40, 40-150, and 150-600 ohms, so that every headphone will receive the legendary McIntosh sound quality and performance.


USB Input

For enjoying DSD and DXD files, the USB input accepts PCM signals up to 32-bit/384kHz and supports DSD64, DSD128, and DSD256, along with DXD 352.8kHz and DXD 384kHz.

Digital Device Enjoyment

For connecting digital devices, an optical and coaxial input are included, along with the USB and MCT inputs; two analog inputs are also available. Headphone Crossfeed Director brings added dimension to your music in a natural sounding way, but can be turned off depending on your preferences. The MHA150 is smaller than other amplifiers in the McIntosh line, giving you additional flexibility to place it almost anywhere in your space.

Ultimate Sound

The MHA150 is powerful and versatile enough to drive a pair of quality desktop or small bookshelf speakers via its 50-watt stereo speaker outputs. McIntosh's patented Power Guard technology is included, and will prevent clipping that could damage your headphones or speakers. A 5-step Bass Boost Control allows for further sound customization.

Beautiful Finish

The entire unit is housed in a beautiful polished stainless steel chassis that not only complements the classic glass front panel, knobs, and brushed aluminum end caps, but virtually any room décor.
