High Notes

Classic British Sound Personified

The CXA81 personifies the best of British sound. It lets all of the emotions of the performers without adding any coloration at all.

Great Input/Output Set

5 Analog inputs, 3 digital, USB, and Bluetooth HD give you everything for a modern music system. Plus you even get a preamp out and subwoofer out. The addition of Bluetooth HD in the new model was a real plus for a lot of systems too!

Massive Power Reserves

The CXA81 has a very large toroidal transformer and a very beefy power supply. It sounds effortless on just about any speaker out there with the ability to drive it to high levels without any sense of strain.

How do you take an admired and successful integrated amplifier, one that’s won respect and plaudits around the world, and make it even better? Well, if you’re a Cambridge Audio engineer, you examine every aspect of the performance - and then you do everything you can to make it ‘more’. More refined, more precise, more engrossing... more musical. CXA81: it’s everything you loved about CXA80, but more so.
