Cambridge audio CXA60 vs CXA80
The Cambridge Audio CXA60 review will focus on design, features and functions. The Cambridge Audio CXA80 tests will show the advanced features and its benefits.
The differences:
The first difference between Cambridge Audio CXA60 vs CXA80 is that the Cambridge Audio CXA80 has 20W more power per channel. Both these amps use toroidal transformers which minimize noise and have higher efficiency.
Between Cambridge CXA80 and CXA60, the CXA80 transformer is more powerful than CXA60 and has 50% volt-amp capacity. Cambridge Amplifier CXA80 has two additional ports which increase versatility when compared with Cambridge Amplifier CA60.
The transformer is intentionally placed far from the preamp circuitry to get rid of any electromagnetic interference. It has an asynchronous USB audio input (USB 1.0 and 2.0) and one balanced XLR input.
With the Bluetooth port, you can play 24-bit/192kHz high-resolution files via PC, Laptop. You can choose the Class 1 or Class 2 mode from the front panel. The balanced XLR connection enhances the audio quality with the original and uncolored sound.
This will helps you if you have long lengths of cables. Also, the XLR is capable of connecting high-end sources. The CXA80 amp has a dual mono design. If you look into the design of the Cambridge CXA80 amp, you will see that the stereo channels are powered independently by two different PCBs.
with the use of an independent transformer, twin rectifier, and independent PSU for the left and right channel, the CXA80 outperforms CXA60 in terms of stereo imaging and separation. If you want to switch between XLR or RCA connections, you need to press the A1 button.
You can also push the input button to select Bluetooth or USB. Blue means RCA/Bluetooth selection and red stand for XLR/USB. With the help of the Control Bus connection, you can connect with other CX products like the CXC or CXN.
Are there any similarities?

Factors to consider while buying an amplifier
The following criteria should be taken into account while choosing an amplifier.
Amplifier power
A 100W or 200W amplifier doesn’t make much of a difference. Just because the power is doubled, doesn’t mean the amp becomes twice as powerful. The 200W amp can play music 3dB louder than the 100W which is almost unnoticeable.
However, amplifier power is a crucial factor to take into account. It depends on speaker sensitivity and your room size. A 15W to 20W amp power is enough for small bookshelf speakers.
If you have large tower speakers, or bookshelf speakers that seek high power, then you may need a 200W amplifier. It will vary from speaker to speaker.
Connections
Since you will be connecting several devices with your amplifier, make sure your amp has ample connections to support these. For instance, with Cambridge Audio CX81, you need a turntable with phono preamp built-in in it.
Different amps have different connection options. RCA inputs are needed to connect audio sources, A phono input is used for a turntable that doesn’t have phono preamp. For some users, USB connection is important to connect to the PC.
Balanced XLR is very popular which is needed to pair high-end devices. Other standard connections include, subwoofer out, preamp out, A+B speaker, etc.
Wired or wireless
If you want to go both wired and wireless, make sure the amplifier has built-in Bluetooth of the latest version. Older amplifiers like Cambridge Audio CXA61 didnt have built-in Bluetooth. So, you need to pay extra and buy a separate Bluetooth dongle.
Along with being Bluetooth compatible, make sure the amp will connect to Bluetooth devices faster and provide stable and consistent connection. However, if wireless isnt an issue for you, you can totally skip this part.
Aesthetics
Since you will be placing and using the amplifier with all the equipment in your home theatre or sound system, the looks will matter. If you have tight spaces, make sure to choose a sleek and slim amp.
You can choose a specific colour to blend with the system. Cambridge Audio CX amplifiers are built with high-quality material. The cabinet is strong enough to deliver service year after year.
Other features
Amplifiers support 4ohm or 8-ohm speakers. The user manual will have a detailed description which you should follow thoroughly.
Other things are important while choosing an amplifier like amplifier class. There are several types (Class A, Class D, Class A/B.) and each has its own pros and cons.
Parting words:
Cambridge Audio CXA81 vs CXA61, which is better? The answer is simple. The specs aren’t night and day so it comes down to personal preference and critical listening. It also depends on your speakers.
Standard bookshelf speakers or small tower speakers will work great with the CXA61. However, if you have speakers that are demanding, or have <88dB efficiency speakers, then going with CXA81 is a better choice.
The major differences between the Cambridge Audio CXA81 vs CXA61 lie in power, connections, and dual mono design. The CXA81 has a warmth in its tone so if you are expecting an ‘attack-on-your-face’ sound, then it is not for you.
Bluetooth connectivity in these amplifiers allows seamless connectivity with all wireless devices. In terms of performance to price ratio, we are pretty much satisfied with these products.
The CXA61 is for those who love to dance to the rhythm and enjoy a musical tone. Whereas the CXA81 is for powerful speakers and will sound a bit ‘recessed.
