    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.”

    Hervorragende Leistung und Klang

    Habe den Verstärker im Oktober gekauft, bin immer noch begeistert: der Anschluss eines PC über USB oder eines Mobilgeräts über Bluetooth war problemlos. Der Klang ist überragend, der Verstärker holt aus meinen eher preiswerten Lautsprechern heraus, was geht. Die Lautsprecher (ca. 10 Jahre alt, ca. 400 €/Stück) werde ich sicher noch gegen bessere ersetzen, aber der Tausch des Verstärkers war schon ein großer Sprung. Der USB-DAC führt zu fein aufgelösten präzisen Tönen in allen Bereichen, und man hört den Unterschied zwischen Spotify (compressed, verlustbehaftet) und Tidal Hi-Fi oder Tidal Master sehr deutlich. Die Bedienung mit der Fernbedienung ist unkompliziert. Für meine Zwecke reichen Anzahl und Art der Eingänge völlig aus, möglicherweise fehlt dem einen oder anderen ein HDMI-ARC-Eingang. Ich wollte Stereo Hi-Fi, das hab ich bekommen, das ist überzeugend gut.
    Habe den Verstärker an Weihnachten noch um einen CXN ergänzt, der ergänzt das ganze ebenfalls sehr überzeugend.

    CXA81

    This is my first hi-fi, having come from home theatre before. The Cambridge amplifier has excellent sound quality. I also like the subdued looks of the unit.

    Choosing input numbers rather than input type (cd, phono) seems a good design choice, to avoid anything looking dated in the future.

    Having a second pair of balanced inputs might be nice.
