Rediscover Music with Edge

Cambridge Audio's refined monoblock power amplifier, the Edge M offers the same rhythmic coherence and depth of image as the rest of the Edge range, but with the power in reserve to drive even the most demanding of speakers.

The Power to Deliver

A pair of Edge M Monoblock Power Amplifiers have the power in reserve to drive even the most demanding of speakers with punch and clarity. Because each Edge M is fully balanced from input to output, they are immune from noisy distortion and free to deliver your music exactly as the artist intended - nothing added, nothing is taken away - whatever the volume.

Muscle with Finesse

As powerful as a pair of Edge M amplifiers can be, they remain remarkably detailed. The sound is finely balanced with a depth and clarity that comes through with every note. Cambridge developed the whole Edge system by carefully listening to each component and only choosing the ones that blew them away. Nothing was picked on price or specs. The end result is a power amplifier that brings the original recording to life in a truly spectacular fashion.

Short and Sweet

Although minimal in its exterior design, Edge M has some complex audio engineering inside. To remove the barriers between you and your music, Cambridge has worked hard to minimize the number of components in the signal path. As a result, Edge M delivers a more faithful reproduction of the original recording; an impressively detailed three-dimensional sound, with striking staging and focus.

More Musical Detail

Cambridge pioneered the use of toroidal transformers in amplifiers, which led to improved performance. In Edge, this was taken one step further, using opposing symmetry twin toroidal transformers. This cancels out electromagnetic interference while 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 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 the most versatile Preamplifier Network Player, Edge NQ, to create a hi-fi system with a sound, and a look, unlike anything else.
