Different price classes - Cambridge Audio CXA61 costs roughly 2.8x what Cambridge Audio AXA35 does. Expect it to lead on paper; the question is whether you will hear the difference through the speakers you own.
| Area | Better | Why |
|---|
| Power | B | Cambridge Audio CXA61 has more power - 60W against 35W into 8 ohms. That is about 2.3dB, so it plays usefully louder before it runs out and has more in hand on peaks. |
| Room size | depends | We rate Cambridge Audio AXA35 the better fit for desk or near-field listening, and Cambridge Audio CXA61 for a very large room. Match the amplifier to the room you actually have, not the one you want. |
| Speaker load rating | B | Cambridge Audio CXA61 is rated down to 4 ohms against 8, so it is the safer partner for a low-impedance speaker. |
| Noise floor | B | Cambridge Audio CXA61 is the quieter design on paper - 105dB against 82dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | B | Cambridge Audio CXA61 has a DAC on board; the other needs an external one, which is another box, another power lead and another purchase. |
| Analogue inputs | evenly matched | The same number of line-level inputs (5). |
| Phono stage | depends | Cambridge Audio AXA35 has a built-in phono stage (MM,MC) and Cambridge Audio CXA61 does not. Decisive if you own a turntable, completely irrelevant if you do not - and an outboard phono stage is easy to add later either way. |
| Room to grow | B | Only Cambridge Audio CXA61 offers preamp outputs - which decides whether you can add a subwoofer or a power amplifier later without replacing the box. |
| Price | A | Cambridge Audio AXA35 costs less - $399 against $1,099 at list. |
| Watts per dollar | A | Cambridge Audio AXA35 is the cheaper watt - about $11 per watt against $18. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A Cambridge Audio AXA35 B Cambridge Audio CXA61
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both amplifiers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Cambridge Audio CXA61 measures better, Cambridge Audio AXA35 costs about 64% less. With most speakers in most rooms that gap is smaller in practice than it looks here. Start with the room. In a large or open-plan room, or with speakers that are hard to drive - low sensitivity, or an impedance that dips - Cambridge Audio CXA61 has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 35 watts is already more than most people ever use, and the extra 25 watts would be headroom you pay for and never hear. If you play records, Cambridge Audio AXA35 saves you buying a phono stage; if you do not, ignore that row entirely.
What a spec sheet cannot show: how either sounds with your speakers, how the controls feel day to day, and what the app is like to live with - which is where most all-in-one amplifiers are actually won or lost. Power figures are the manufacturers' own and are not measured to a common standard, so treat small differences as noise. If you can hear both, that will tell you more than any row above.
