Pros
Combines sweet, expressive valve character with powerful, controlled solid-state drive and convincing dynamic slam.
Produces an expansive, deeply layered soundstage with exceptional lateral scale and depth.
Bass is deep, weighty and controlled, with a rounded musical character rather than mechanical sterility.
Superb fit and finish, plus useful analogue facilities including balanced inputs, MM phono, sub outputs, HXD headphone output and five-band EQ.
Cons
No digital inputs, DAC or streaming, so digital-first systems require an external source component.
Moving-coil cartridge users need an external phono stage; the built-in input is MM only.
Its relaxed, soft-edged voicing trades some midrange openness and treble attack for long-listening smoothness.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 94/100
The MA352 is widely described as a smooth, warm and highly engaging hybrid, combining valve sweetness with solid-state grip and scale. Reviewers especially praise its powerful, controlled bass, expansive three-dimensional presentation, clear detail and ability to remain composed at high levels; the main tonal caveat is a slightly relaxed, soft-edged character rather than an aggressively forward one.
Transparency Resolution
93/100
Tech Reviews calls the presentation clear enough to reveal both nuances and details, while SoundStage Solo hears a sweet sound that still retains detail and resolution. Pursuit Perfect System similarly finds abundant microdetail and clear treble, although its delivery is deliberately delicate rather than incisive.
Tonal Balance Musicality
92/100
Reviewers consistently hear a warm, smooth and musical balance, with rich bass and midrange, silky treble, and particularly appealing vocal reproduction. SoundStage Solo notes a mild upper-bass warmth without boom, while Pursuit Perfect System characterizes the sound as romantic and laid-back; listeners seeking a more immediate or overtly open midrange may prefer a different voicing.
Dynamics
94/100
The 200W-per-channel hybrid is repeatedly praised for effortless authority, clean slam and stable composure as volume rises. SoundStage Solo highlights its convincing orchestral crescendos and dynamic realism, while hi-fi+ found no shortage of drive even with demanding speakers.
Soundstage Imaging
95/100
Spatial performance is a standout. Tech Reviews heard a large, airy image with exceptional depth, SoundStage Solo describes massive lateral scale and depth among the best in integrated amplification, and Pursuit Perfect System praises its notably deep, three-dimensional stage extending beyond the speakers.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
92/100
The reviews describe a substantial, solidly made 30kg amplifier with a high-quality polished stainless-steel chassis and rugged fit and finish. There is one practical usability complaint: the unmarked tone-control knobs can be moved while cleaning, making precise settings difficult to restore.
Features Connectivity
90/100
This is a well-equipped analogue-focused integrated amplifier, with balanced and unbalanced line inputs, an adjustable-loading MM phono stage, preamp and dual-subwoofer outputs, Home Theater Pass Through, a capable HXD headphone output, and five-band tone control. It omits digital inputs, DAC, streaming and an MC phono input, so source components for digital playback remain necessary.
Value for Money
91/100
At roughly £8,995 / €6,990 / AU$13,995 depending on market, it is plainly a premium purchase, but reviewers see a persuasive case within McIntosh's range. hi-fi+ says it belongs on a buyer's shortlist at its price, while Pursuit Perfect System regards it as a very good-value route to the larger McIntosh sound and power for substantially less than the MA12000.

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.
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 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 MA352 is packed with numerous McIntosh technologies including:
- Our patented Power Guard technology that monitors the output signal for over driving and makes real time micro adjustments to the input signal to prevent harsh sounding clipping that could potentially damage your speakers
- Our fuse-less short-circuit protection circuit Sentry Monitor that will disengage the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal
- McIntosh Monogrammed Heatsinks which are connected to advanced high current output transistors that minimize thermal equilibrium lag (or warm-up) time
- High Drive headphone amplifier with Headphone Crossfeed Director (HXD
- A 5-band analog tone control allows for manual adjustment of your favorite recordings (each band adjustable by ± 12dB)
- Home Theater Pass Through lets it be seamlessly integrated into a home theater system
- Power Control to send power on/off signals to connected McIntosh components for easy system power up and shutdown
- Data Ports to send remote control commands to connected source components
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 playersturntablestunersmedia streamers and speakers to complete your home audio system. Contact your local dealer to learn more.
