    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.

    EDGE
    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.

    Personal Audio

    Hong Kong SAR China,

    「Cambridge Audio 的音響故事始於 1968 年,來到 2018 年,意味着品牌迎接五十週年,新旗艦 Edge 系列成為最佳賀禮,回望品牌根源,向創辦人之一的 Gordon Edge 致敬,再展望下一個五十年。之前在不同場合聽過 Edge NQ 串流前級、Edge W 後級推動 B&W 803 D2,新旗艦的聲音的確超越 Cambridge Audio 以往產品,而且幅度頗大。因此,在試聽 Edge A 合併機前,還以為可以預計它有何等表現,結果是出乎意料,被它直接打臉!」
