McIntosh MC901 Amplifier

The MC901 integrates both tube and solid-state amplification into a single chassis, which eliminates the need for external crossovers and complex cabling. By housing both sections in one unit with independent power supplies, it ensures perfect synchronization and simplifies the bi-amping process significantly.

The built-in adjustable crossover allows you to precisely define the frequency range sent to the tube and solid-state sections. You can fine-tune these settings using the accessible controls on the unit to match the specific requirements of your loudspeaker's drivers.

Vacuum tubes are renowned for their warm, natural, and detailed sound reproduction, which is ideal for the delicate mid and high-frequency drivers. By dedicating the 300-watt tube section to these drivers, the MC901 delivers a more nuanced and lifelike performance.

Yes, the MC901 is designed to deliver its full power into 2, 4, or 8-ohm loads. Thanks to McIntosh’s Autoformer technology, the amplifier maintains consistent power delivery regardless of the impedance of your connected loudspeakers.

The MC901 is specifically engineered for bi-amping applications where the loudspeaker has separate inputs for the woofer and the mid/high sections. It is not intended for use with speakers that only feature a single set of binding posts.

The 600-watt solid-state section provides the high current and power necessary to drive woofers with authority and control. This ensures deep, tight, and impactful bass response that complements the refined character of the tube-powered mid and high-frequency section.
