A Real Power Player

True audiophile headphone performance begins and ends with the amp that drives the show.  If you’re looking for superior performance, then McIntosh’s MHA150 Headphone Amplifier is an easy choice.  Sporting an elegant exterior adorned with classic McIntosh appointments, the MHA150 offers a visual appeal that complements any room decor.  Using the company’s second-gen digital-to-analog converters (DACs) and a robust amp section, authentic levels of detail are revealed from any source. 

A Legendary Name in Audio

The blue glow that emanates from a McIntosh watt meter is a symbol of serious sound quality that’s recognized by audio aficionados around the world.  Founded in 1949, McIntosh has consistently been an industry leader, setting standards for sound quality, craftsmanship, and reliability.  The company still hand makes each of its spectacular audio components in Binghamton, NY, with an unwavering commitment to delivering the best audio experience possible. 

Robust Physical Appearance

McIntosh components are more than just high performance gear, they’re physical works of art.  Sitting at a foot wide and weighing nearly 27-pounds, the MHA150’s compact stainless steel chassis is a sight to behold.  The amplifier’s gorgeous glass front panel shares center stage with a pair of the company’s classic blue meters, green logo, a multifunctional display, brushed aluminum knobs, and basic controls.  It’s an attention-grabbing package that pleases the eyes as much as it pleases the ears. Front panel lighting is achieved through using a combination of fiber optic light diffusers and long lasting LEDs.

Reference Performance Under the Hood

Using an adapted version of the same Autoformer technology found in McIntosh’s larger amplifiers, the MHA150 delivers the perfect amount of power to any headphone.  And to make sure your personal headphones are accommodated, output can be adjusted to meet the demands of three different impedance ranges, including 8-40, 40-150, and 150-600.  

True versatility is introduced by dual 50 Watt speaker outputs that can drive external speakers, giving the MHA150 unparalleled universal appeal.  Keeping inline with McIntosh’s luxurious design factors, speakers connect via gold plated terminals that accept large diameter wire and spade lugs. And if you’re looking for a little more low end, just tap the included preamp outputs for access to an external powered subwoofer. 

Feed Any Source

McIntosh designed the MHA150 to handle audio material from every conceivable source.  The rear panel carries optical, coaxial, USB, and MCT inputs for digital devices, along with RCA and XLR analog connections.  These give the MHA150 the ability to receive input from sources ranging from compact disc players to smart phones, and all of your preferred analog sources. McIntosh’s new 2nd generation DAC offers access to DSD and DXD files, with support for resolutions up to 32-bit/384kHz.

Easy Feature Control

If you’re searching for total relaxation during music sessions, sit back, relax, and use the included remote to control your listening experience.  Users can remotely adjust output volume and input selection, but also can gain access to various Trim Functions that alter bass output, balance, and other amp features.  

Customize Your Sound

The included Headphone Crossfeed Director (HXD) can be activated to improve sound localization while listening with headphones.  Activating HXD brings depth and spaciousness to your headphone sound, with imaging that rivals performance from conventional speakers.  Owners can also adjust a 5-step Bass Boost feature that increases the intensity of low frequency sound in increments of 2.5 decibels. 

Durable Protection Circuits

McIntosh endowed the MHA150 with several technologies to keep your gear safe.  The onboard Sentry Monitor Protection Circuits safeguards headphones in situations where there’s an impedance mismatch, while Power Guard prevents clipping that can damage headphones and speakers.  Both technologies allow you to use the MHA150 with peace of mind.

Your Headphones Deserve Only the Best

If you’re seeking total headphone luxury and superior audio, look no further than McIntosh’s stellar MHA150 headphone amp.  Not only does it present McIntosh's trademark style, it also delivers unique technologies and elegant performance you’d expect from the industry’s leader in audiophile design.
