MSB S202 Stereo Amplifier
Innovation. Redefined.
After the astounding success and performance of the S500 Stereo Amplifier, we set our sights on expanding that sound into more systems. Trickle-down technologies incorporated into a more compact, lower-power framework resulted in the S202 Stereo Amplifier. It’s capable of meeting our DAC’s ultra high dynamic range head-on with optimized architecture in the critical areas of audio performance, power supplies, and ultra low-noise design. The S202 includes a fully modular design, matched impedance input stage and an all billet CNC case. The highest value amplifier we’ve ever created, the S202 redefines excellence and sets a new bar in the industry.
Thanks to a massive custom low-noise high-current toroidal transformer and rugged high-current output buffers, the S202 provides a transparent, holographic listening experience that’s completely fatigue free. This ensures that the amplifier presents consistent performance even with difficult speakers.
The S202 features a discrete design with a Class-A matched impedance input stage. The result is a product with minimized signal reflections, input noise, and distortion, while also maximizing power transfer and dynamic range in a zero negative feedback design. All components were meticulously chosen for their sonic performance and longevity, ensuring your amplifier is built to last. The S202 amplifier is designed and lovingly crafted in our factory based in California. After 14 hours of CNC machining, a complete chassis of billet aluminum components are ready, maximizing heatsink area with a stunning visual profile. This high-efficiency design provides a surface area of over 3,000 in² per amplifier. High-power heat pipes distribute heat evenly for optimal thermal and electrical performance. Elegant yet commanding, our finishes are available in a matte silver or matte black anodize. Our products include our in-house designed viton feet, but any audiophile M6X1 foot can be installed to personalize your system.
The S202 is equipped with a simple, user-friendly control interface. Intuitive push buttons, remote commands, and the 12V triggers guarantee control over power and standby modes. Further control of amplifier “power on” timers and soft-start circuits allow a multi-amplifier system to power up without putting strain on your listening room’s electrical system.
Intuitively oriented speaker lugs direct your speaker cables in the right direction without strain. Multiple ground posts enable EMI reduction strategies, including shielded cables and system star grounds.
