The McIntosh MC2105 is one of the most beloved solid-state classics in the Mac lineup—those iconic blue meters, the glass faceplate, and a sound that defined an era of American hi-fi. Delivering 105 watts per channel with that unmistakable McIntosh smoothness, the MC2105 is known for its rich midrange, unfatiguing highs, and bass that’s warm, confident, and wonderfully musical.
This unit has been electronically restored, including the critical replacement of the large filter capacitors, giving it the stability, punch, and low-noise performance it deserves. With fresh power reserves and updated internals, it plays with greater authority, clarity, and ease—while retaining every bit of that classic Mac character.
A beautifully revitalized piece of hi-fi history, ready for decades more of those soft-glowing, blue meter-dancing nights.

- Liner Notes
The MC 2105 is completely stable when connected to any loudspeaker system or even to any reactive loads; The amplifier has special circuits to prevent damage by short circuit or open circuit of the output loads, or by any amount of output impedance mismatch, Thermal cutouts are mounted on the output transistor heat sinks to provide protection in the event of inadequate ventilation.
- Shipping
- To ensure safe arrival, we often use private couriers. These are transporters in Sprinter Vans or pulling covered trailers often moving art and antiques across the country. Absolutely the safest way to ship short of you picking it up yourself. This piece ships to the contiguous United States for a flat rate of $380, which includes our packaging and our insurance. Of course, we'll ship anywhere in the world, just drop us a line and we'll give you an estimate – even if you're just curious.
