      Edge A Integrated Amplifier

      Breathtaking 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.

      EDGE

      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.
