McIntosh MC-275VI Tube Power Amplifier

The McIntosh MC275 75 W/ch Tube Amplifier represents the sixth generation of one of the most celebrated stereo power amplifiers in high-end audio history. Delivering 75 Watts per channel of refined tube power, the MC275VI retains the classic sonic warmth that music enthusiasts adore while introducing modern engineering enhancements for quiet, low-distortion audio reproduction. Built on a mirror-polished chassis with a durable aluminum side plate, this stereo power amplifier brings music to life with remarkable depth, clarity, and control.

At the heart of the McIntosh MC275 is an advanced output transformer design with wide bandwidth capabilities, offering tauter bass control and smooth high-frequency response. A thermally quiet circuit design minimises background noise, allowing subtle musical details to emerge from a black background. Preamplifiers connect seamlessly through balanced XLR or unbalanced RCA inputs, while patented gold-plated speaker binding posts ensure tight, low-resistance connections for optimal signal transfer.

Seven small vacuum tubes line the front of the chassis, equipped with LED illumination to indicate functional status. Upon power-up, the tubes sequentially glow amber during the warm-up cycle before switching to green when operational readiness is reached. If an output tube issue occurs, the corresponding LED indicators switch to red to notify you immediately. Integrated Power Control ports allow remote illumination and power management directly from a compatible preamplifier.
