The M205 Mono Amplifier MSB Technology, December 14, 2021

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 our 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 we’ve ever created.

Power without limits.

This ensures that the amplifiers present consistent performance even with difficult speakers.
