The McIntosh MA12000 combines a vacuum-tube preamplifier with a 350-watt-per-channel solid-state power amplifier. Its Hybrid Drive architecture places four 12AX7A tubes in the preamplifier section and uses McIntosh Autoformers to deliver the rated output into 2-, 4-, or 8-ohm loudspeakers.
Seventeen analog and digital inputs make the MA12000 a comprehensive system center. The included DA2 Digital Audio Module supports files through 24-bit/192kHz and DSD512, while two phono inputs, an eight-band analog equalizer, balanced and unbalanced outputs, and a dedicated subwoofer output provide room for a carefully planned system to grow.
