Rotel Michi S430 Stereo Power Amplifier

The Rotel Michi Prestige S430 Stereo Power Amplifier brings commanding power, refined control, and elegant high-end engineering to premium two-channel audio systems. Rated at 230 watts per channel into 8 ohms, with 390 watts per channel maximum output into 4 ohms, the S430 is designed to drive high-performance loudspeakers with authority, dynamic headroom, and musical precision. Its Class AB amplifier design is supported by an oversized in-house manufactured toroidal transformer, high-efficiency bulk storage capacitors, symmetrical circuit traces, and carefully selected signal-path components for faithful music reproduction. Balanced XLR and unbalanced RCA inputs, dual 5-way speaker binding posts, 12V trigger control, a front-panel TFT display, and an included remote control make the S430 a powerful and polished centerpiece for a serious stereo system.
