MSB Technology
MSB Mono Amplifiers
Thanks to two massive custom low-noise high-current toroidal transformers and rugged high-current output buffers, the M205’s provide a transparent, holographic listening experience that’s completely fatigue free. This ensures that the amplifiers present consistent performance even with difficult speakers.
M500 Mono Amplifier
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 optimised in critical areas, audio performance, longevity, and an ability to drive any speaker became MSB's principal design parameters.
M205 Mono Amplifier
Impressive Performance. Compact Mono Design.
Innovation. Redoubled.
After the resounding success of the S202 Stereo Amplifier, there were many requests for an improved mono amplifier in the same compact chassis. The M205 refines the S202’s already incredible performance with an upgraded input stage and a doubling of the power supply transformers and capacitors. The result is a spectacular increase in sound quality with increased sound-stage definition, vocal realism, and instrument solidity available from the very first notes. The M205 perfectly complements MSB’s DAC’s ultra high dynamic range with optimized architecture in the critical areas of audio performance, power supplies, and ultra low-noise design. The fully modular cores, matched impedance input stages and billet CNC chassis’ result in the highest value mono amplifiers MSB has ever created.
Input Architecture.
The M205 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.
Billet CNC Chassis.
The M205 amplifiers are designed and lovingly crafted in their factory based in California. After 28 hours of CNC machining, two complete chassis’ of billet aluminium 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.
Core Values.
Building the M205 amplifiers with core enclosures greatly improves 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 M205’s are equipped with simple, user-friendly control interfaces. Intuitive push buttons, remote commands, and the 12V triggers guarantee control over power and standby modes. Further control of amplifiers “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. With dual outputs, the M205 is ideal for a bi-amped system. Multiple ground posts enable EMI reduction strategies, including shielded cables and system star grounds.
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.
M500 Mono Amplifier
Superior performance. Amplified.
Powered by Innovation
MSB redefined the idea of what an amplifier can be, embedding the M500 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 M500 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 M500 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 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 square inch 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.
