Cambridge Audio pioneered the use of toroidal transformers in amplifiers, which led to improved performance. In Edge we take this one step further, using opposing symmetry twin toroidal transformers. This cancels out electromagnetic interference whilst offering outstanding power and maintaining consistent tonality, no matter how loud it’s played.

Effortless Power Without Distortion

Using standard Class A amplifier technology wasn’t going to be efficient enough for Edge M. Instead, Cambridge Audio added a bias voltage to a traditional Class AB design, reducing distortion to inaudible levels. This unique configuration also produces less heat and makes the whole system much more effective.

Perfect Partners

Edge systems are designed to work in perfect synchronization. Match a pair of Edge Ms with Cambridge Audio's most versatile Preamplifier Network Player, Edge NQ, to create a hi-fi system with a sound, and a look, unlike anything else.
