STEG MSK1500

The STEG MSK1500 from the exclusive Master Stroke series is a high-end Class A/B 2-channel amplifier designed without compromise, combining the highest sound quality with tremendous power. Designed and manufactured in Italy, this power amplifier combines high-quality audio components, a sophisticated power supply, and state-of-the-art amplification technology for high-end car audio systems.

With an output power of up to 2 × 400 watts RMS into 2 ohms and an impressive 1,500 watts RMS in bridged mode into 2 ohms, the MSK1500 offers exceptional power reserves. The sophisticated triple-Darlington output stage, carefully selected components, and the stabilized P.R.H.E.S.S. power supply ensure precise, dynamic, and exceptionally detailed music reproduction.

The integrated G.R.I.P.S. system minimizes electromagnetic interference, while the active, temperature-controlled cooling ensures reliable operation even under heavy load. Extensive filtering options, an adjustable bass equalizer, and high-quality connections round out the overall audiophile design.
