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. Pioneered the use of toroidal transformers in amplifiers, which led to improved performance. In Edge Cambridge Audio 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. 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. 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. Edge A was designed with a unique PCB. Cambridge Audio engineers replaced conventional capacitors with a DC coupled topology and also added a solid-state volume control. The result is a clean signal path that’s perfectly balanced at any volume. Edge systems are designed to work in perfect synchronization. Match the performance of Edge A with loudspeakers to make the foundations of a hi-fi system unlike anything else.
