Superior performance. Amplified.
Powered by Innovation
The world’s leading DACs needed an amplifier to match. The result was a clean slate design that could meet MSB's DAC’s ultra high dynamic range head on. With the amplifier’s architecture optimized in critical areas, audio performance, longevity, and an ability to drive any speaker became MSB’s principal design parameters. They redefined the idea of what an amplifier can be, embedding the S500 with a fully modular design alongside a 1.0 Farad Power Core, a matched impedance input stage and an all billet CNC case. The finest amplifier they have ever created, the 500 series redefines excellence and sets a new bar in the industry.
Design without Compromise
The S500 features a discrete design featuring a Class-A matched impedance input stage. This 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. With custom low-noise high-current toroidal transformers and rugged high-current output buffers, the S500 provides a transparent, holographic listening experience that’s completely fatigue free. All components were meticulously chosen for their sonic performance and longevity, ensuring your amplifier is built to last.
Billet CNC Heatsink
The 500 series amplifier is designed and lovingly crafted in MSB’s factory based in California. Each of the heatsinks start out as a 51lb aluminium block before sixty percent is removed over eight hours of machining, resulting in 17.5 lbs of refined aluminium. This high efficiency design provides a surface area of over 10,000 sq in per amplifier. What’s more – the fin thickness is slightly varied to help reduce resonances and ringing in the heatsinks, while multiple high power heat pipes distribute heat evenly for optimal thermal and electrical performance.
Core Values
Building the 500 series amplifiers with a core enclosure greatly improved their reliability and performance. Upon completion, the cores are rigorously tested and stocked for orders, ensuring the highest quality product is ready at a moment’s notice. With this segmentation, your system is optimized for performance and resilience.
Smart Control Features
The S500 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.
Powerful Configurations
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. A 20 amp IEC connection is provided for high current delivery, while three gain settings optimize dynamic range for any speaker.
Anodized Finishes
Elegant yet commanding, MSB’s finishes are available in a matte silver or matte black anodize. MSB’s products include their in-house designed viton feet, but any audiophile M6X1 foot can be installed to personalize your system.
The 12V Trigger Adapter
The 12V trigger adapter provides a multitude of ways for connecting your MSB product with other 12V trigger systems.
