The McIntosh MC250 is a vintage solid-state classic that captures the smooth, effortless sound McIntosh Laboratory became famous for in the late ‘60s and early ‘70s. With its compact chassis, iconic glass front panel, and unmistakable McIntosh styling, the MC250 delivers a warm, musical presentation that feels far bigger than its modest power rating suggests. It’s the kind of amp that pairs beautifully with efficient speakers, bringing out rich mids and relaxed detail that make long listening sessions easy—and for vintage hi-fi fans, it’s a piece of American audio history that still sounds wonderfully alive today.

- Liner Notes
The McIntosh MC2505 is a solid state power amplifier with a maximum power output of 100 watts RMS continuous, 50 watts per channel operating simultaneously, into 4 ohm, 8 ohm, or 16 ohm loads. Harmonic distortion is less than 0.25% at rated power output from 20Hz to 20,000Hz. Frequency range at rated output both channels; +0, 0.025dB, 20Hz through 20,000Hz. At around serial number 36K00, the model designation was changed to 2502-2, and can be visually identified by flush meters, and a gain knob that runs clockwise from -20dB to 0.
