With a design that puts its analog vacuum tube power on full display, New York-based high-end audio brand McIntosh has combined a 300-watt tube amp with a 600-watt solid state amp into one eye-catching monoblock unit called  the MC901 Dual Mono Amplifier. The solid state amp powers  your woofers while the tube amp is dedicated to mid & tweeters. Built on a stainless steel chassis, it blends retro styling with a functional, contemporary design.
