Model: Edge A
Edge A is made to celebrate musicality. Riffs, phrases, percussive rolls – take in every detail of your music thanks to its dynamic setup. Effortlessly powerful, but with incredible depth, the overall sound is breath-taking – like you’re sat in the recording booth with the musicians.

Breath-taking musicality.

Edge A is designed to bring musical detail to life. It delivers a finely balanced sound with a depth and clarity that come through with every note. We developed the system by ear, testing every component and only choosing those that blew us away. The end result is a ground-breaking arrangement that produces a much cleaner signal path and lets your music breathe. Edge A perfectly delivers our classic British sound – nothing added, nothing taken away.

More musical detail.

We 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 A. Instead we 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.Hi-res bluetooth.

Pair any Bluetooth device to your Edge A to easily stream your music. With aptX HD support, you can play your audio at up to 24-bit/48kHz quality for an incredibly rich listening experience.

Sonic balance.

Edge A was designed with a unique PCB. Our engineers replaced conventional capacitors with a DC coupled topology and also added a solid state volume control. The end result is a clean signal path that’s perfectly balanced at any volume.

Perfect partners.

Edge systems are designed to work in perfect synchronisation. Match the performance of Edge A with loudspeakers to make the foundations of a hi-fi system unlike anything else.
