McIntosh MA2375 Vacuum Tube Integrated Amplifier
The McIntosh MA2375 Vacuum Tube Integrated Amplifier is a 2-channel, all-analog integrated amplifier designed for listeners who want the rich, dimensional character of vacuum tube sound with the control, flexibility, and reliability expected from McIntosh. As McIntosh’s first vacuum tube integrated amplifier in over a decade, the MA2375 combines a vacuum tube preamplifier and vacuum tube power amplifier in one striking component, delivering 75 watts per channel into 4, 8, or 16 ohms through McIntosh Unity Coupled Circuit Output Transformers.
Its tube complement includes two 12AX7A and two 12AT7 preamp tubes, plus four KT88 output tubes and four 12AT7 driver tubes, creating a full-bodied, low-distortion listening experience across a wide range of speakers. The polished stainless-steel chassis, dual McIntosh blue watt meters, and warm tube glow make the MA2375 a centerpiece for premium two-channel listening rooms.
For connectivity, the MA2375 includes six analog inputs, including balanced, unbalanced, and a configurable universal phono input for Moving Coil or Moving Magnet cartridges. A 5-band analog equalizer, High Drive headphone amplifier with HXD, subwoofer output, Home Theater PassThru, RS232 control, Power Control, Data Ports, and Solid Cinch speaker binding posts make this vacuum tube integrated amplifier both refined and highly adaptable.
What It's Good At:
- Delivering warm, immersive vacuum tube sound from both the preamp and power amp stages.
- Driving a wide variety of speakers with 75 watts per channel into 4, 8, or 16 ohms.
