(June 3, 2026) McIntosh has unveiled the MA2375 2-Channel Vacuum Tube Integrated, its first all-tube integrated amp design in more than a decade. In a market increasingly filled with streaming amps that feature touchscreens, companion apps, and digital conveniences, the MA2375 takes a decidedly different approach. There are no digital inputs, built-in streaming capabilities, or fancy DACs. It's unapologetically analog, designed for listeners who still find something magical in the warm glow of vacuum tubes.
The entire chassis houses a tube preamp and tube power amplifier as a single unit, harnessing a total of 12 vacuum tubes. Up front are a pair of 12AX7A and 12AT7 tubes dedicated to preamp duties. Around back, four additional 12AT7 driver tubes and four KT88 output tubes provide the muscle. The result is a healthy 75 watts per channel, which may not sound like much in an era of 300-watt solid-state amplifiers. Yet for an all-tube integrated amp, it's a significant amount of power, enabling the MA2375 to drive a wide range of loudspeakers while preserving the character that attracts many listeners to tube amplification in the first place.
McIntosh's long-running Unity Coupled Circuit output transformer technology is in play. Output transformers are among the most critical components in any tube amp, acting as the bridge between the tubes and your speakers. McIntosh has spent decades refining this in-house approach, and the company says the MA2375 can deliver its full rated output to 4, 8, or 16-ohm speakers, depending on which output taps are used.
Of course, let's be honest: part of the appeal here has very little to do with specifications. This is the kind of gear people buy because it looks like living, breathing audio art. The MA2375's polished stainless steel body, exposed tubes, removable rear protective cage, and iconic blue power meters create an unmistakable visual presence that's all McIntosh through and through. It's definitely not something you stash away in a cabinet. In fact, McIntosh recommends nearly 19" of overhead clearance between the MA2375 and any topside surface, because those KT88 output tubes can generate meaningful heat!
To that end, McIntosh has built in several layers of operational protection. Its Power Guard Screen Grid Sensor continuously monitors the KT88 output tubes and helps prevent them from being driven beyond safe operating limits, while Sentry Monitor provides fuse-less short-circuit protection. So rest assured, McIntosh is giving you tools to keep the MA2375 healthy and capable of running for years to come.
Connectivity remains focused on the needs of traditional audio enthusiasts. Six analog inputs are onboard, including balanced XLR connections and a configurable phono stage that supports moving magnet, high-output moving coil, and low-output moving coil cartridges. In fact, Vinyl listeners can adjust gain, capacitance, and loading directly through the amplifier, eliminating the need for a separate phono preamp stage.
Now, before you pigeonhole the MA2375 as a modernized Hi-Fi relic, there are a few modern touches worth pointing out. A mono subwoofer output is included, as is Home Theater PassThru for integration into surround systems. McIntosh has also incorporated a five-band analog equalizer, allowing listeners to make tonal adjustments without introducing digital processing into the signal path.
What's perhaps most interesting about the MA2375 is what it says about possibilities within today's higher-end market. In a time where convenience often dominates product development, McIntosh is betting that there's still a healthy audience willing to build a system around a component that values craftsmanship, longevity, and musical engagement above all else.
The MA2375 will be available from McIntosh dealers beginning in June 2026. For pricing and local availability, contact your local dealer.
