McIntosh Labs have created some of the most important amplifiers in the audiophile world. And this one is their most powerful to date. The MA 12000 is a 350 watts per channel beast, with a warm vacuum tube pre-amplifier and a solid-state amplifier with two 12AX7A tubes per channel. There are 10 analog inputs in the back as well as seven digital inputs that include a USB and an audio-only HDMI ARC for connections to your TV. The unit also includes a high-drive headphone amp for premium private listening. And McIntosh amps always look as good as they sound, as exemplified by the MA 12000's glow of vacuum tubes, signature blue watt meters, and two-line status display out front.
