    Rewarding Performance 

    Our CXA81 integrated amplifier builds on the foundations laid by the first CX Series, and over 50 years’ experience of building amps. It offers a progressive perspective – effortless, poised and sophisticated. 80 watts per channel give CXA81 complete authority over music, to reveal every emotion and nuance from your whole music collection – be that streamed or on disc.

    CX Black Edition

    We present a 1000-piece limited edition of each CX Series 2 model in a minimalist matt black finish, with discreet gloss black branding. The same award-winning sound as CX, only in black. Why? Because we thought they’d look dead cool. If you want some, please don’t delay – CX Black Edition won’t be here for long.

    Effortlessly Musical

    At the heart of CXA81 beats a Class AB power amplifier stage with optimised capacitor values. It takes the musicality of Class A and blends it with the efficiency of Class B. The amp’s short signal path is efficient, leaving little opportunity for interference. The resulting sound is pristine while delivering the emotional impact the artist intended.

    Power with Control

    Thanks to a generous toroidal transformer, CXA81 delivers a prodigious 80 watts of power per channel. Dual taps into the left and right of the amplification board mean that, in effect, each channel has its own power supply – resulting in a vivid sound stage. Dynamic shifts in music – like those loud then quiet moments – are handled with ease.

    • Superb Amp. I Can’t Stop Smiling

      "I bought this amp a week or so ago and cannot recommend it enough. The clarity, soundstage and depth are a giant stride better than my old amp. Everything is so tight and crisp. Digital or vinyl it’s like I’m listening to my music collection for the first time.”

    Lovely Jubbly

    It is Christmas morning & like a kid in a sweetshop! Ac/Dc has been rocking away very nicely indeed. Bon Scott sounds even better now! Must thank my better half so much! But thank you too Cambridge Audio, you got me sold on this CXA81 my previous was a 640A pre amp. Loved it 2 bits also.. I am so lucky to have a partner like I do!

    Je suis comblé

    Après une vingtaine d'année avec une installation home cinéma (Denon + B&W), j'ai abandonné cette installation et voici 3 ans que je me suis redirigé vers la hifi. J'ai donc acheté le CXA81 ainsi que le CXC. J'auditionne donc uniquement des CD avec une paire d'enceinte Bowers & Wilkins 606. Je suis comblé par le son et je regrette de ne pas m'être dirigé plus tôt vers cette solution. L'amplificateur Cambridge est très qualitatif et exploite à merveille les possibilités des CD les mieux gravés. Basses (même à faible volume), médiums, aigus, présence sonore, séparation des canaux ! Tous ces éléments sont là avec une grande qualité. Bravo Cambridge !
