Return on Investment
Cambridge Audio's 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 is selected and decisions are 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 optimized 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.
