Stereo Box S

Value-based audiophile integrated amplifier


This compact integrated stereo amplifier achieves both a sound quality and SPL output that belies its small size. Designed around a Bi-Phase PWM (Pulse-Width Modulation) digital amplifier circuit, the Stereo Box S achieves a remarkable 80% operational efficiency and a highly dynamic 30 watts per channel output into 4 ohms. The shielded metal chassis protects the circuitry from vibration and electromagnetic interference for the highest fidelity possible. A remote control adjusts volume and can switch inputs.
