The best Cambridge power amplifier to date

The Edge W is designed for listening to music at full volume. When you do, you will enjoy a dynamic and powerful sound with all the musicality of your songs. With just 14 carefully selected components, the Edge W has one of the cleanest signal paths available. It offers the amazing unadulterated British Sound of Cambridge, without additions but without missing anything.

Powerfully subtle

Despite its great power, the Edge W offers a sound with great nuances. The sound is perfectly balanced, with musical depth and clarity that comes through in every note. This is possible thanks to the way in which Cambridge has chosen the components: never by price, specifications, or the measurement of their performance. The British listened rigorously. And they created their system with components that sound unbeatable. This results in a power amplifier that brings original recordings to life like no other.

Only 14 components in the signal path

Although minimalist on the outside, the Edge W has a complex audio system inside. To remove the barriers that separate you from the music, Cambridge have worked hard to minimize the number of components in the signal path.

As a result, the Edge W offers a more faithful reproduction of the original recording; a three-dimensional sound with an impressive level of detail and surprising staging and concentration.

More musical nuances

Cambridge has been pioneers using toroidal transformers in amplifiers, which has achieved better performance. With the Edge range they go one step further, using double toroidal transformers of opposite symmetry. This cancels out electromagnetic interference while delivering exceptional power, maintaining consistent tonality, regardless of the playback volume level.

Effortless and distortion-free power

Using standard Class A amplification technology has not been efficient enough for the Edge W. Instead, Cambridge has added biasing to a traditional Class AB design, reducing distortion to make it inaudible to the human ear. Additionally, this unique configuration produces less heat and makes the entire system much more efficient.
