Signature McIntosh Performance and Design
McIntosh Unity Coupled Circuit Output Transformers help the MA2375 maintain consistent performance across a wide range of loudspeakers, allowing the amplifier to deliver its full musical character with confidence and control. This performance is matched by an unmistakable McIntosh presence, with dual blue watt meters, a polished stainless-steel chassis, and the warm glow of vacuum tubes reflecting the brand’s balance of classic craftsmanship, modern refinement, and timeless high-fidelity design.
Pure Tube Architecture
Inside the MA2375, the power amplifier section is driven by four KT88 output tubes, supported by four 12AT7 driver tubes to deliver the strength, control, and musical expression expected from a true vacuum tube amplifier. The preamplifier section uses two 12AX7A and two 12AT7 tubes, helping preserve tonal richness, fine detail, and the natural sense of depth that make tube amplification so engaging.
Seen through the polished chassis and glowing tube array, the MA2375 reveals the beauty of McIntosh’s analog engineering. Each tube is carefully positioned not only for performance, but also to create a visual experience that reflects the amplifier’s character — warm, refined, and unmistakably handcrafted.
This tube configuration allows the MA2375 to shape music with a rich tonal balance, expressive dynamics, and a spacious presentation. From delicate vocal textures to powerful instrumental passages, the amplifier is designed to bring a greater sense of presence and emotion to every listening session.
Personalized Listening and Flexible Connectivity
For sound personalization and private listening, the MA2375 features a 5-band analog equalizer and High Drive headphone amplifier with Headphone Crossfeed Director, or HXD®. It also offers flexible analog connectivity, including six analog inputs, a configurable phono input for Moving Coil and Moving Magnet cartridges, a subwoofer output, and an unbalanced preamplifier output for expanded system configurations.
Built for Confidence and Easy Integration
Built for lasting confidence, the MA2375 includes Power Guard Screen Grid Sensor® technology to help protect the KT88 output tubes, along with Sentry Monitor™ short-circuit protection. Power Control, Home Theater PassThru, Data Ports, RS232 control, and the included remote control make it easy to integrate the amplifier into a refined home audio or home theater system.
