McIntosh was originally founded in Silver Spring, Maryland, in 1949. The current Binghamton, NY factory continues to grow with the company. ‘Heritage’ refers to places and values past established that continue to influence the operation and culture of McIntosh today. The McIntosh founding fathers created a solid foundation based on sound business and scientific principles that continue to guide the company.
The people behind the scenes at McIntosh possess a desire to achieve the finest quality standards. McIntosh has defined quality sound reproduction and sets the standards for performance, reliability and service. McIntosh has handcrafted prestige audio products in Binghamton, NY since 1949. Glassfront panels, Output Autoformers®, Blue Watt Meters and Power Guard® are some of the innovations that enhance their product longevity.
Handcrafted in America since 1949, McIntosh is known for offering distinguished quality audio products, superior customer service and the ultimate experience in music and film. McIntosh continues to define the ultimate home entertainment experience for discriminating consumers around the world, with the iconic "McIntosh Blue" Watt Meters globally recognised as a symbol of quality audio. Since its inception, McIntosh has been powering some of the most important moments in music history and pop culture. From President Lyndon Johnson’s inauguration speech to Woodstock to the infamous Grateful Dead “Wall of Sound,” McIntosh has not only witnessed history, it has shaped it. In 1969 McIntosh Amplifiers powered Woodstock, a pivotal moment in Music history. Three days of peace, love and music for the hundreds of thousands who attended.
Over the years, many famous musicians, recording artists and producers have selected McIntosh audio systems for the rich quality of sound, to experience music the way the artist intended. The loyalty from the music community began in the 1960s era of rock and roll. Several of their brand ambassadors have shared their experience and passion for McIntosh which has often spanned across decades.
The MA252 Integrated Amplifier is the first hybrid integrated amplifier from McIntosh. Taking retro design cues from the legendary McIntosh MC275 Vacuum Tube Amplifier, the MA252 combines the best of vacuum tube and solid state circuit design to create an amplifier that’s both visually and sonically stunning.
The preamplifier stage uses two 12AX7a and two 12AT7 vacuum tubes housed inside stylish protective cages; the output stage is a direct coupled solid state amplifier that delivers 100 Watts per channel into 8 Ohm speakers or 160 Watts per channel into 4 Ohm speakers. An all analog design, it comes with 2 unbalanced, 1 balanced and 1 Moving Magnet phono input for turntables. All 4 inputs can be given user-friendly names in order to simplify user control. Bass and treble tone controls help fine tune your music to your personal preferences. A full range subwoofer output is included for use with a powered subwoofer to further enhance low frequencies.
The MA252 features our McIntosh Monogrammed Heatsinks™ which are connected to advanced high current output transistors. These transistors eliminate the typical amplifier warm-up time so that the MA252 is in peak operating condition from the moment it’s turned on. A powerful control microprocessor is used for smooth system operation, along with some of the latest audio-grade circuit components that deliver the best possible sound.
Thanks to its solid state output, the MA252 is our first product containing vacuum tubes to include our patented Power Guard® technology. Power Guard monitors the output signal for signs of overdriving and makes real time micro adjustments to the input signal to prevent harsh sounding clipping that could potentially damage your speakers. If Power Guard is activated, the 2 vacuum tubes connected to the affected audio channel(s) will flash an amber colour; they will return to their normal green colour when the clipping has stopped.
Other McIntosh technologies found in the MA252 include Sentry Monitor™, High Drive headphone amplifier and gold-plated speaker binding posts. Input selection, bass, treble, tone bypass, balance and input offset levels can be adjusted using the front panel knobs or the included remote control; all settings and input selection will be shown on the OLED display. The entire unit sits atop a beautiful polished stainless steel chassis with a classic McIntosh-styled die cast aluminium name badge attached to each side
