Overview

The MA352 Integrated Amplifier is a hybrid design that combines the finest of vacuum tube and solid state audio design principles. The result is an eye-catching amplifier that enjoys the best of these two opposing audio philosophies all while reproducing music at the highest quality level.
"Want valve [vacuum tube] sound with solid state power and reliability? McIntosh have a long history in both fields and bring their expertise to glorious fruition in the audacious MA352 hybrid amplifier, packed with power, glowing valves and the expansive sound they enjoy... The MA352 is an amplifier that we thought was glorious in both appearance and sound." Named Best Hybrid Amplifier 2020.– Hi-Fi World

The MA352 has "everything it takes to become an instant classic." - Audio Review
The MA352 includes our Hybrid Drive™ technology that uses the best of vacuum tubes and solid state to produce the best sound performance. An all analog design, the MA352 has a vacuum tube preamplifier section that is powered by a pair of 12AX7A and a pair of 12AT7 vacuum tubes; its output stage is a direct coupled solid state amplifier that outputs 200 Watts per channel into 8 Ohm speakers or 320 Watts per channel into 4 Ohm speakers – enough power to properly drive virtually any set of loudspeakers. Dual scale blue Watt meters give an accurate readout of power output for both speaker impedances.
"The hybrid McIntosh amplifier is powerful enough to power your favorite speakers, and refined enough to make the experience memorable, no matter what kind of music you play. Highly Recommended." - Lyd & Bilde

"It is a no nonsense pure analogue amplifier design that does exactly what it should do and that is power your speakers to very high levels without any kind of distortion but with exceptional accuracy and clarity to the music." Winner of Reference Award - The Speaker Shack
The MA352 has 2 balanced and 3 unbalanced inputs plus 1 Moving Magnet phono input with adjustable loading for connecting a turntable. It has gold-plated speaker binding posts to help prevent corrosion and ensure a quality signal is sent over your speaker cables to your speakers. A stereo preamplifier output is available for connecting a higher-powered amplifier; it can also be used to connect 1 or 2 powered subwoofers for added low frequency performance.
"The quality of the sound never falters. The MA352 remains stunningly clear and detailed with loads of power to spare. With the MA352's impressive 0.03% THD and IMD, you’ll be hard pressed to find any distortion even at window shaking volume." - Tone Audio

"There’s a sense of confidence in the amplifier’s effortlessness in terms of its power capabilities and its handling of music, how it functions and its overall execution. It offers a rounded set of features. It’s solidly built and assembled. It looks gloriously attractive. Finally, and most importantly, it plays music to very high standards of dynamic realism, tonal accuracy and sheer listenability." - SoundStage Australia
The MA352 is packed with numerous McIntosh technologies including:
The MA352 "allows you to experience music to the fullest by letting the dynamics and all the energy, as well as the subtleties and slightest nuances, be expressed freely. The width of the soundstage, balance of the frequency ranges, precision of the timbres, impact of the lows and clarity of the highs: the McIntosh MA352 combined all of these qualities with ease, no matter the style of music we listened to." - Son-Vidéo
"There is no compromise here in terms of sound and aesthetics but if you are looking to make a statement on both, this is the integrated amplifier for you." Highly Recommended. - HiFi and Music Source
The unit sits on a stainless steel chassis polished to a mirror finish; vintage McIntosh-styled die cast aluminum name badges are affixed to each side. Blue output meters, control knobs, an illuminated logo, and a black glass front panel with direct LED backlighting complete the unit. It can be paired with an assortment of CD players, turntables, tuners, media streamersand speakers to complete your home audio system. Contact your local dealer to learn more.
