    Return on Investment

    Our engineering team in London invested hours researching, developing, experimenting and, above all, listening to ensure that CXA81 was right.

    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.”
