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.

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.

Anodized finishes.

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.
