Did you ever want an amplifier that makes all other muscle amps look a bit silly? Like toys? Then read on...

Featuring incredibly over-engineered and sophisticated dynamic power supplies, bridged SECA circuits, fully dual mono. The audio circuit requires very little negative feedback. With both RCA and balanced XLR input.

The M-100 and the same M-100 Turbo both produce class A for a good part of their total output and as such, present extraordinary insight into music and the space it occupies. Dynamics as presented by an M-100 can be startling and visceral whilst completely effortless. It is often the case that listeners finds themselves enjoying music at much higher volume levels than they think, such is the clean power delivery and genuine level of dynamic realism on offer here.


The power available means music is utterly huge in scale, and transient events will shock without incurring the slightest hint of listener fatigue. This power, while extreme for sure, translates into clean and believable music at any volume. This amplifier just won't stop.

The Turbo version is the ultimate upgraded version of the M-100, capable of producing fifty percent more power with its massively sophisticated power supply. It will dominate completely any loudspeaker. Integrated DC blocking and mains control is standard. 


Now available with 'Sense' - feed forward error correction. This corrects for any loss detected at the loudspeaker terminal when compared to the amplifier input. Ask for more details about the M-100 Turbo S option.

These amplifiers produce some heat due to class A operation, but are actually incredibly efficient due to their sophisticated power supply and thermal management. They barely get warm compared to valve designs or less resolved push-pull designs.
