McIntosh has unveiled the MA2375, its first new tube integrated amplifier in more than a decade. The new model combines classic McIntosh vacuum tube technology with modern protection systems, extensive connectivity, and the unmistakable styling that has made the American manufacturer one of the most recognizable names in high-end audio.
With an output of 75 watts per channel and a fully analog signal path, the MA2375 is designed for listeners who want the warmth and musicality of tube amplification without sacrificing power or versatility.
The McIntosh MA2375 is the company's first new tube integrated amplifier in more than a decade, combining classic vacuum tube sound with modern engineering.
Classic Tube Technology Meets Modern Engineering
At the heart of the MA2375 is a carefully selected tube complement consisting of four KT88 output tubes, four 12AT7 driver tubes, and a combination of 12AX7A and 12AT7 tubes in the preamplifier stage.
Like many of McIntosh's most celebrated tube amplifiers, the MA2375 uses the company's proprietary Unity Coupled Circuit output transformers. This design allows the amplifier to deliver its full 75-watt output into 4, 8, or 16-ohm loudspeakers, providing greater flexibility when matching the amplifier with different speaker systems.
McIntosh has long regarded its transformer technology as a key element of its tube amplifier designs, helping maintain consistent performance regardless of speaker impedance.
Four KT88 output tubes and McIntosh's renowned Unity Coupled Circuit transformers deliver 75 watts per channel into 4, 8, or 16-ohm speakers.
Built-In Protection for Tubes and Speakers
To ensure long-term reliability, the MA2375 incorporates several of McIntosh's latest protection technologies.
The amplifier features Power Guard Screen Grid Sensor (SGS), which continuously monitors the output stage and helps prevent premature tube wear caused by excessive drive levels. It is joined by the company's well-known Sentry Monitor protection system, designed to safeguard both the amplifier and connected loudspeakers from electrical faults without relying on conventional fuses.
These technologies allow users to enjoy the character of tube amplification with added peace of mind.
A built-in five-band analog equalizer allows listeners to fine-tune the sound to match their room, speakers, and personal preferences.
Phono Stage, Equalizer and Headphone Features
Unlike many modern integrated amplifiers that increasingly focus on digital features, the MA2375 remains firmly dedicated to analog audio.
The rear panel includes multiple analog inputs and outputs, a dedicated phono stage for turntable enthusiasts, subwoofer outputs, data ports, and RS232 connectivity for custom installation environments.
One of the more unusual features is a built-in five-band analog equalizer, allowing listeners to fine-tune the sound to better suit their room acoustics, loudspeakers, and personal preferences.
Headphone users are also catered for through McIntosh's Headphone Crossfeed Director (HXD) technology, which aims to create a more natural stereo presentation that more closely resembles listening through loudspeakers.
With a dedicated phono stage, subwoofer outputs, and premium analog connectivity, the MA2375 is designed as the centerpiece of a serious audiophile system.
Iconic McIntosh Styling
Visually, the MA2375 stays true to the brand's heritage. Exposed vacuum tubes sit proudly on top of the chassis, while the signature blue analog meters dominate the front panel.
The amplifier is housed in a polished stainless-steel enclosure and features premium gold-plated speaker terminals, combining classic aesthetics with the robust build quality expected from a flagship McIntosh product.
The McIntosh MA2375 marks the brand's return to tube integrated amplifiers with 75 watts per channel, KT88 tubes, premium analog features, and timeless McIntosh design.
Price and Availability
The McIntosh MA2375 is expected to retail in the United Kingdom for £16,900. With its combination of traditional tube amplification, modern protection technology, and unmistakable McIntosh styling, it is positioned as a premium option for audiophiles seeking a high-end all-analog integrated amplifier.
