McIntosh launches MA2375 tube integrated amplifier

McIntosh has introduced the MA2375, a 2-channel vacuum tube integrated amplifier built around an all-analog signal path. The new model combines a vacuum tube preamplifier and vacuum tube power amplifier in a single chassis, with rated output of 75 watts per channel. It is McIntosh's first vacuum tube integrated amplifier in over a decade.

The amplifier uses McIntosh Unity Coupled Circuit output transformers and supports 4-, 8-, and 16-ohm loudspeakers. Its tube complement comprises four KT88 output tubes, four 12AT7 driver tubes, two 12AX7A preamp tubes, and two 12AT7 preamp tubes. The design is analog-only, with no DAC, digital input, or streaming capability.

Connectivity includes six analog inputs, split between two balanced inputs, three unbalanced inputs, and one configurable universal phono input for moving-magnet or moving-coil cartridges. Other listed features include a subwoofer output, an unbalanced variable preamp output, a 5-band analog equalizer, and a High Drive headphone amplifier with HXD. Protection and connection features include Power Guard Screen Grid Sensor, Sentry Monitor, and Solid Cinch speaker binding posts.

The closest official predecessor context is the MA2275, a McIntosh 2-channel vacuum tube integrated amplifier manufactured from 2004 to 2011 with the same 75 watts per channel output rating. In the current McIntosh integrated-amplifier lineup, the MA2375 sits among models using vacuum tube, Hybrid Drive, solid-state, and streaming architectures. Availability began 3 June 2026 through authorized McIntosh dealers.
