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 McIntosh's 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.

OVERVIEW

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. 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.

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 (HXD®) 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 McIntosh's other amplifiers, giving you additional flexibility to locate it almost anywhere in your space. It’s the same width as the MB50 Streaming Audio Player and the two can be combined to start building a complete system.

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. 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.

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