”More than justifies the outlay once more.” ’What Hi-Fi?’ 2022 Product of the Year.

The amp that does it all

Engineered to the highest standards, the CXA81 delivers class-leading sound quality. The 80 watt amp is powerful enough for the largest rooms and the most power-hungry speakers. A built-in ESS DAC (Digital to Analogue Convertor) means you get the best from your digital, as well as analogue sources. Thanks to standard Bluetooth, you can now stream music in top quality aptX HD. All this, plus the Lunar Grey CXA81 looks more stylish than ever.

Powerful sound from the toroidal transformer
Powerful sound begins with the power supply, which is why Cambridge Audio use an audiophile quality, toroidal transformer. Renowned for their low noise, high efficiency and superior sound quality, the over-sized transformer gives the CXA81 a powerful, dynamic sound and a hefty 80W per channel power output - enough for ‘party level’ sound in even the largest domestic spaces.

Digital inputs with top spec DAC for detail
Featuring a reference standard ESS Sabre ES9016K2M DAC, the CXA81 works wonders with your digital audio and video sources. With two optical digital inputs and one coaxial, you can connect up to three digital sources, such as a games console, TV and a CD transport – the Cambridge Audio CXC makes the perfect match.

Bluetooth as standard
Now a standard fitment, Bluetooth offers simple, wireless music streaming from your mobile, tablet or laptop. Stream stored music or popular music streaming services such as Spotify, Tidal and Apple Music. The Bluetooth receiver is compatible with aptX HD, giving the highest quality sound possible from Bluetooth, right up to 24bit/48kHz. You also get the benefit of the sound passing through the ESS Sabre DAC, meaning precise, detailed sound from all your streamed music.

The best from USB audio, with Hi-Res sound
If you enjoy Hi-Res sound, you’ll love the CXA81. Using an asynchronous USB socket at the rear, you can connect up to your laptop, PC or server and stream Hi-Res music, right up to studio-quality 32bit/384kHz and DSD256. As well as improving the sound over your computer’s soundcard, the asynchronous ‘direct control’ link also greatly reduces jitter, for lower distortion and more precise audio.

Professional connection
More usually found on 'reference' hi-fi and professional equipment, the CXA81 boasts balanced XLR inputs. When connected to a suitable source, this gives a fully balanced, hot/cold, connection for the ultimate analogue signal quality.

All for analogue
The Cambridge CXA81 has four line level inputs - enough for all your analogue sources. A pre-amp output is also fitted – ideal for power amp upgrades. Other handy connections include an RCA subwoofer output, headphone socket and connections for two pairs of speakers.

Connected for installs
A wide range of control sockets make the CXA81 ideal as part of a more complex home installation. RS-232C, IR input, trigger in/out sockets and Control Bus RCA phonos mean the CXA81 is more than happy to work with a wide range home automation control systems.

Vibration resistant casing
With rigid, metal construction and low-resonance design, the casing helps shield the player from both mechanical and electrical interference, helping to improve clarity and reduce background noise. Isolating feet help adsorb vibration for a further reduction in distortion.

Sleek new finish
The CXA81 is part of the refreshed CX-Series 2. The distinctive tear-drop profile gives the CXA81 a contemporary look and makes it the ideal partner for the CXC CD transport, CXN V2 network player. The Lunar Grey front panel contrasts with the black top and sides and blends well with both black and silver separates.

Complete versatility meets the finest sound, with the Cambridge Audio CXA81.

Rated 5 out of 5 by from Great amp but no tape 2 loop or rec out facility. Good balanced detailed sound. However I was advised by RS that I could use the pre amp output to connect to a recording device as it is a line level output. This is not correct as the preamp output depends on the setting of the volume control. There is no equivalent tape 2 loop facility as such. This is the only drawback. Other users may not require this facility.
