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.
This beautifully crafted integrated amplifier includes our Hybrid Drive technology that uses the best of vacuum tubes and solid state to produce the best sound performance. 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 over driving 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 color; they will return to their normal green color 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 aluminum name badge attached to each side. Contact your local dealer to learn more.

Cons
- Not an infinite power source—bass weight and dynamics can diminish with very demanding speakers or at extreme listening levels.
- No digital inputs or upgradeable DAC module, which limits flexibility for digital-first users.

Dynamics
89/100
The 100 W/8Ω solid‑state power stage delivers strong dynamic headroom for its class; reviewers reported being able to 'crank it up' without clipping and praised its punch and control. Several reviews noted excellent dynamic power and headroom, while a few comparisons to much more powerful separates hinted at slightly less ultimate slam at the very highest levels.
Soundstage Imaging
90/100
Multiple reviewers described a multi-dimensional, immersive presentation with good depth and well-placed images (What Hi‑Fi: separates musical strands; HiFi News: lets you 'walk around' elements of a mix). While not the absolute widest/deepest staging compared with high-end separates, imaging is precise and engaging for most listening contexts.

Features Connectivity
88/100
A solid analogue-focused feature set: balanced XLR input, two unbalanced RCAs, a capable MM phono stage, 1/4" high-drive headphone out, and a mono subwoofer output plus tone controls and input renaming. No digital inputs or upgradeable DAC module limits versatility for digital-first users, but included analogue & headphone features are well implemented.
