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.
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.
‘The way this amp lays out all the detail in front of you and yet delivers it all in a cohesive fashion is nothing short of breathtaking.’
“While the integrated amplifier market gets ever more crowded, the Cambridge Audio Edge A stands out with its stunning good looks and equally lush sound quality.”
'From the very moment it touched down on my doorstep, something told me that the hefty Edge A integrated amp was going to be something very special indeed.'
'[Edge A is a] stunning new integrated amplifier. Cambridge Audio has long held the reputation of making affordable giant killers. In its 50th year, it made its own giant, and even that is still a giant killer in its own right.'
'Cambridge Audio's most powerful and detailed integrated amplifier ever...'
'...If you were to build out the perfect hi-fi system for your dream house, this amplifier would probably be at its heart.'
'If I were in the market for an amp to enlighten these dark winter nights, this would be my choice.'
'I've reviewed many integrated amplifiers for Stereophile.....none provided me with as much simple, exuberant, at times jaw-dropping fun as Cambridge Audio's Edge A.'
'50 years of Cambridge Audio, [and] it was worth waiting for this amplifier. With the Edge A, the British brand once again prove their outstanding expertise for high-class audio technology at an unrivalled price point.'
'Cambridge Audio make themselves and their fans a birthday present and release the best amplifier ever developed by the British company: musical, vivid and extremely dynamic.'
'[It's] impossible not to be fascinated by the Cambridge Edge A... Cambridge Audio [has] set a benchmark... Excellent measurements demonstrate that the developers (whose signatures are to be found on the circuit boards) have done a brillant job...'
「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！」
