McIntosh MA2375: Fully Analog, Fully Integrated
The McIntosh MA2375 is a fully analog vacuum-tube integrated amplifier and McIntosh’s first vacuum-tube integrated amplifier in more than a decade. It brings a vacuum-tube preamplifier and power amplifier together in one component, delivering 75 watts per channel through McIntosh Unity Coupled Circuit Output Transformers. Dedicated 4-, 8-, and 16-ohm speaker connections make the rated output available across those specified loads.
The MA2375 is equipped to serve as the analog center of a carefully planned stereo system. Two balanced and three unbalanced line inputs accommodate multiple sources, while the configurable phono input supports moving-magnet, low-output moving-coil, and high-output moving-coil cartridges with adjustable capacitance, resistance, and gain. A five-band analog equalizer provides tonal adjustment at 30 Hz, 125 Hz, 500 Hz, 2 kHz, and 10 kHz. Twin McIntosh Watt Meters display left- and right-channel output in watts and decibels.
