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.

McIntosh Labs MA352 2-Channel Hybrid Integrated Amplifier
A potent hybrid that marries vacuum-tube preamp warmth with transistor power, the McIntosh MA352 delivers commanding authority and refined musicality. Blending a tube-driven front end with a 200 W per channel solid-state output, it combines valve sweetness with tight, controlled bass, articulate mids and clear, non-fatiguing treble. Reviewers at hi-fi+, SoundStage Solo and Pursuit Perfect System praised its effortless dynamics, expansive, three-dimensional soundstage and dependable headroom. Physically the MA352 is textbook McIntosh—polished stainless steel, blue VU meters and monogrammed heatsinks—while practical touches include an adjustable MM phono, dual sub outputs, Home Theatre pass-through and a High Drive headphone stage with HXD. Ideal for listeners who need drive for large speakers, vinyl playback and late-night headphone use, the MA352 pairs classic McIntosh charisma with modern solidity.
Pros
- Exceptional power and dynamic headroom—200 W/8 Ω (320 W/4 Ω) gives confident control and effortless transient delivery suitable for demanding speakers.
- Warm, musical midrange with clear treble and wide, well-layered soundstage—valve front end provides body while the solid-state stage keeps detail and control.
- Class-leading build and McIntosh styling with practical analogue features—polished stainless chassis, blue VU meters, adjustable MM phono, HXD headphone stage and sub/home-theatre pass-through.

Cons
- No built-in moving-coil (MC) phono input, limiting direct high-output MC cartridge support for vinyl purists.
- Limited digital connectivity—no onboard DAC, USB or digital inputs, so digital sources require an external DAC or streamer.
- Five-band analogue tone controls lack precise markings and can be inadvertently altered during cleaning or handling.

Dynamics
93/100
Across reviews the MA352 is repeatedly praised for its effortless, powerful delivery and headroom — phrases like 'immediate effortlessness', 'massively-scaled', and 'never had cause to doubt that it had more than enough driving power' appear. The hybrid topology (tube preamp, solid-state power with 200W/8Ω / 320W/4Ω) and high damping factor support the impression of strong transient control and authority.
Soundstage Imaging
91/100
Multiple reviewers highlight expansive lateral width, depth and three-dimensionality: 'massive soundscapes', 'depth and three-dimensionality', and 'impressive extended width to the sound stage.' Imaging is described as stable and capable of rendering orchestral scale as well as intimate layering of vocals and instruments.

Build Quality
93/100
Build is described as class-leading McIntosh — heavy, solid, chromed stainless-steel chassis with signature VU meters and monogrammed heatsinks; reviewers note the premium finish and robust construction ('impressively solid', 'superbly finished yet rugged'). Tube implementation and thermal considerations are noted as well-executed.
Features Connectivity
90/100
Features are rich for a primarily analogue hybrid: two balanced XLR and multiple RCA inputs, an adjustable-loading MM phono stage, High Drive headphone amp with HXD, 5-band analogue EQ, Home Theatre Pass-Through, preamp/sub outputs and data/RS232 ports. No built-in DAC or streaming module limits digital connectivity but the analogue feature set and useful extras (dual sub outs, tone bypass, power/control ports) make it well-equipped.
Value for Money
90/100
Reviewers in multiple regions call the MA352 'very good value' relative to larger McIntosh models and its performance: comments include 'you'd be crazy not to put it on your shortlist' and 'very good value for a big power McIntosh.' While the price varies by market (reviews cite AU$13,995, US $12,995 and UK £8,495–£8,995), sentiment is that the performance justifies the premium.
