MA2375 2-Channel Vacuum Tube Integrated Amplifier

The MA2375 is an all-analog vacuum tube integrated amplifier that combines a vacuum tube preamplifier and vacuum tube power amplifier in a single chassis. Introduced as McIntosh's first vacuum tube integrated amplifier in over a decade, the MA2375 is designed to deliver the musicality of tube amplification with the convenience of an integrated design. The amplifier features McIntosh's iconic output meters, a built-in 5-band analog equalizer, dedicated phono input with adjustable loading and gain, and multiple balanced and unbalanced analog inputs.
