McIntosh MC2301 1-Channel Vacuum Tube Amplifier

  • 300 Watt Quad Balanced Monoblock
  • Vacuum tube powered


From the demands of massed chorale to full-on rock and roll, the MC2301 delivers the most extraordinarily lifelike and dynamic performance ever heard from a McIntosh tube amplifier. With an output of 300 Watts, it provides enough high power to drive even the most demanding loudspeaker. And thanks to our patented Unity Coupled Circuit output transformer, this full 300 Watts is available to 2, 4 or 8 Ohm speakers.

  • 300 Watt Quad Balanced Monoblock
  • Vacuum tube powered


The MC2301 is the first McIntosh vacuum tube amplifier to use our Quad Balanced design. This design cancels virtually all noise and distortion in the audio signal. As a result, even when amplified to high levels the signal is effectively free of any distortion. Our fuse-less short-circuit protection circuit Sentry Monitor™ disengages the output stage before current exceeds safe operating levels and then resets automatically. Inputs for balanced and unbalanced cables are available to provide flexibility in connecting the rest of your audio system.


The attractive blue meter is flanked by two rows of output vacuum tubes that bring even more visual appeal to the front panel to go along with the knobs and brushed aluminum handles that all effortlessly blend with the polished stainless steel chassis. The MC2301 is well suited for stereo music systems. Contact your local dealer to learn more.
