    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.

    Return on Investment

    Our engineering team in London invested hours researching, developing, experimenting and, above all, listening to ensure that CXA81 was right. Their goal: to make the most accomplished and absorbing integrated amp in its class. Every component selected, and decision made, based on the desire to deliver the most complete musical picture possible.

    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.”

    Fantastic amp

    Probably the best amp I have ever bought (and I have had a few). I have it hooked up to my mac by a very good usb cable, so I get 24/192 hires and it sounds amazing. The only thing I would have liked would have been the ability to toggle off the speakers completely but I found a good workaround. I have a few Cambridge products and they are all top notch.

    New CXA-81 Receiver

    It’s a different color than my last one and doesn’t match the CD player. But sounds better than ever.
