WHO IT IS FOR
Who it is for
Primary roles
- Mono power amplification
- Separated left and right amplifier chassis
System contexts
- Two-channel systems designed around one amplifier chassis per loudspeaker
- Systems where channel separation, cable layout and one-chassis-per-speaker architecture justify a stereo pair of M205s.
Consider it when
- Listeners who have the space, support and system context for mono amplifiers
ARCHITECTURE
Understand what each feature means in a complete system.
Selectable input impedance
Input impedance can be set to 75 Ω, 300 Ω or 1.2 kΩ to suit the upstream system.
Class A input, Class AB output
MSB combines a Class A input stage with a Class AB output stage.
SYSTEM / ROOM MATCHING
Will it fit the system you already own?
We consider connections, room context, installation and your listening priorities together before suggesting a configuration.
What to check for your system
- A stereo installation requires two 41 kg chassis with suitable support and ventilation

What to keep in mind
