”Sets a new baseline for integrated amps at this price.” ’What Hi-Fi?’ 2021 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 The best in it’s class As soon as I started this beauty up I was hit with such a powerful and punchy sound. It stands tall with the best and whatever music you play the totally detailed dynamics it presents will not disappoint.. I just love it.

Rated 5 out of 5 by from Great features and a fantastic sound. In the process of replacing Cambridge Audio Azur 640 units purchased from Richer Sounds back in 2007! Kept four Mordant Short Avant 908i speakers. The speakers are in separate rooms so the ability to operate A and B speakers separately on the CXA81 is helpful. The punch and flexibility of the CXA81 particularly with the CXNv2 and StreamMagic is at a new level!

Rated 5 out of 5 by from Great system I bought my new system 2 weeks ago and didn't really know what I was really looking for, other than that I wanted something mid range.. Not cheap but not too expensive. I relied on Archie, the sales assistant at the Reading store to give me some guidance and am really pleased with his advice and choice of equipment to meet my desire. The amplifier, CD transporter and pre amp are now sitting in a cabinet that my father made in 1971, when I was 11 years old. The Garrard turntable is from 1971 also and now works perfectly with the new equipment. I will be needing some speaker stands in the near future, at the moment they're temporarily sitting on the sides of the cabinet. The 2 photos show the new system that I bought from Richer Sounds and the old Nippon Sound amplifier that my father bought in 1978 to replace the original one from 1971.

Rated 5 out of 5 by from A good upgrade I bought the CX81 amplifier to replace my existing CXA80. I own a CXA60 amp also. The CXA60 has a very lively and defined sound whereas the CXA80 has a lot more fine detail and a deeper more powerful bass. I always felt that he CXA80 was a bit soft sounding and lacked the bite of the CXA60. I really wanted an amp that combined the best of each. The CX81 does this and more. It has a real dynamic attack without harshness and the bass is excellent with the depth and power of the 80 but with much better control. I use a pair of Kef R300 large standmount speakers in a 5m x 5.5m room. Using the CX81 on film soundtracks the articulation is excellent and the bass power shakes the room. I was surprised at the level of realism that the CX81 delivers when playing classical guitar music. The detail levels are even better than the CXA80. I use a CA CXC CD transport and now I can hear the recording standard and ambiance of CDs much more clearly. All in all the CX81 is a very neutral amplifier with very good articulation and detail plus very deep bass with good control. The stereo image is also good. The dynamic attack is forceful and precise when the music etc demands this. This is the best amplifier I have ever owned and beats all previous CA amps including an Azur 840 which I previously used.If you have a good source and speakers then the CX81 is a worthwhile purchase.

Rated 5 out of 5 by from Cambridge Audio rocks! Finally upgraded 26 year old Arcam system to Cambridge Audio CXN v2, CXA81, CDC, Solo Phona preamp and Revel Concerta2 F35. Absolutely delighted with sound. Clarity and musicality leaping from speakers. From Vivaldi to Zeppelin, all great.
