Cambridge CXA81 Integrated Stereo Amplifier

Cambridge Audio's Progress of the CX Range

Half a decade after the CX range redefined performance at its price point, it’s time to reimagine, reengineer and reinvigorate. The all-new CXA61 and CXA81 integrated amplifiers build on the foundations laid (and the Awards won) by CXA60 and CXA80, but with a fresh and progressive perspective.

The CXA81 is poised, effortless, and sophisticated. Its 80 watts per channel give it complete authority over music, and it wrings every emotional and musical nuance from your whole collection.

Listen to your music at the best

How do you take an admired and successfully 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. The CXA81: it’s everything you loved about the CXA80, but more so.

An amplifier that is uncompromised and uncompromising

All the research, all the development, all the time and effort that’s been expended on the CXA81 has been for one reason alone: to make this the most accomplished and absorbing integrated amplifier ever offered at the price. Every component selected, and every engineering decision taken is based entirely on the desire to progress. The CXA81 has been designed and specified without compromise, to deliver the complete musical picture.

ESS Sabre DAC Technology Inside

The CXA81 is designed to bring your music to life, no matter how it’s stored. So it features an entirely new digital board, including the cutting-edge ESS Sabre ES9016 digital-to-analogue convertor. This means digital audio files up to a heady 32bit/384kHz, or DSD256, are brought dramatically to life, with every detail and nuance delivered intact and in full. The CXA81 combines unparalleled accuracy with vivid musicality, without sacrificing convenience.

Power and Control

Thanks to numerous improvements and upgrades - and thanks to an overspecified toroidal transformer - the CXA81 delivers a prodigious 80 watts of power per channel. This means the CXA81 has complete authority over even the most demanding speakers, it means big dynamic shifts in music are handled with total control, and it means the whole musical picture is available no matter if you’re playing at discreet background levels or party-time volumes.

Absolute Flexibility

The CXA81 covers all connectivity bases, giving you complete freedom of choice. As well as digital optical and digital coaxial inputs, it features unbalanced stereo RCA inputs alongside balanced XLR sockets - and wireless connectivity via Bluetooth’s cutting-edge aptX HD standard is on board too. So there’s no need to compromise on performance in the name of convenience.

Unmatched Sonic Integrity

At the heart of the CXA81 beats a completely reimagined and redesigned power amplifier stage with optimized capacitor values. The resulting sound is pristine but not clinical, with unrivaled musical coherence no matter the source.
