The all-new M205 Mono Amplifier
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.

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 our 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.
