McIntosh MC1502 Vacuum Tube Amplifier

Thanks to McIntosh’s proprietary Unity Coupled Circuit technology, the MC1502 delivers its full 150 watts of power regardless of whether your speakers are rated at 2, 4, or 8 ohms. You do not need to worry about impedance matching to get the best performance from your system.

This design allows the amplifier to provide consistent power and low distortion across a wide range of speaker loads. It is a hallmark of McIntosh engineering that ensures your speakers receive a clean, stable signal without sacrificing the warmth associated with vacuum tube amplification.

The amplifier features balanced XLR inputs, so it is best paired with a high-quality preamplifier that offers balanced outputs. This setup will help you take full advantage of the amplifier's impressive 112dB signal-to-noise ratio for a quiet, clear listening experience.

The MC1502 is a substantial piece of equipment, measuring 18-1/4 inches wide by 21 inches deep and weighing 53.5 kg. You will need a sturdy, well-ventilated surface that can support its significant weight and allow for proper airflow around the vacuum tubes.

The included stainless steel cage is designed to protect the eight KT88 output tubes and eight signal tubes from accidental contact. While it can be removed for maintenance or aesthetic preference, it is recommended to keep it in place to ensure both safety and the longevity of the tubes.

You can expect a classic, rich tube sound characterized by musicality and depth, but with the power and control typically found in solid-state designs. With a total harmonic distortion of just 0.5%, it offers a refined, accurate performance that remains faithful to the original recording.
