”Rarely does Cambridge fire too wide of the mark, but the Duo hits right at the centre of the target.”– ‘What Hi-Fi’ – 5 Star review.

Quality headphone amp

If you want to hear every nuance and background detail of your favourite music then listening with headphones takes some beating. Use the dedicated headphone amp built into the Duo and you’ll experience a whole new level of detail. With a precise volume control you’ll get exactly the right level – whatever your choice of headphones.

Perfect for amps without a phono preamp built-in
Many amplifiers no longer come with a built-in phono preamp, which is fine if you don’t use vinyl but not so good if you want to spin some records. The Cambridge Audio Duo is a dedicated phono preamp, meaning you can add a record deck to just about any amp or system with a standard AUX input. This means your choice of stereo amp or receiver is greatly expanded and, of course, you can retain the Duo phono preamp if you upgrade your main amp.

Perfect for amps with a phono preamp built-in!
Even if your main amplifier already has a phono preamp built-in, the chances are that the one inside the Duo is considerably better. Using a dedicated, switch mode power supply, the Duo is far quieter than most built-in phono preamps. The revised circuit board layout with surface-mount components further reduces noise and distortion. Factor in the shielded casing and you’ll simply hear more music and less background noise.

MC cartridge compatibility
One of the biggest advances over its little brother, the Solo, is the ability to amplify MC (Moving Coil) cartridges. These have an even lower output than MM (Moving Magnet) cartridges and require dedicated amplification. Once correctly amplified, the sound quality is stunning with a smoother yet more detailed sound. If you're serious about vinyl then fitting a good quality MC cartridge is an upgrade that you won’t regret.

Subsonic filter
Not all records are pressed the same – due to the poor quality of vinyl used, some sound considerably nosier than others. Wear and tear can play its role in reducing the quality, too. With its subsonic filter, the Duo filters out low frequency rumble; reducing distortion and protecting your speakers’ woofers from excessive wear.

Rated 3 out of 5 by from More flexibility neede Beautifully made very good sound if a little “safe”. The output is not enough in my system especially on headphones. I have no doubt the output of my MM cartridge is the problem so a variable output adjustment would be better than the balance adjustment on the rear. The usual efficient and friendly service from Richer Sounds. I will have to sell the unit on sadly.

Rated 5 out of 5 by from What a fantastic phono stage! I had recently upgraded from a CXA60 to a CXA80 and bought the CXNv2 (connected with XLR cables). I have a Project Debut Carbon II turntable and this was hooked up to the Cambridge Audio 651P. It was a very good sound coming through the turntable and amp. However, I decided to look at an upgrade and spoke to Tech Support at Cambridge Audio and decided to bite the bullet and buy the Duo phono stage. The headphone socket and ability to listen with an amp built into the Duo was the deciding factor. It looks and feels very solid and aesthetically is very pleasing. Very easy to set up and had it working within minutes. I compared the sound between the 651P and Duo back to back, starting with The Blue Nile "Tinsel Town in The Rain". The sound stage and separation was markedly better with the Duo and the sound was so clear and there were little accents that came through far clearer. I then put on Kraftwerk "Autobahn" and the punch and bass was fantastic. This album is 44 years old - I bought it in 1974 - so it's had a fair bit of use. What I did notice (quite markedly) was that some of the background noise from the album (clicks etc.) were much reduced with the Duo. I decided to try Pink Floyd "Dark Side of the Moon" which was bought in 1973, followed by David Bowie "Ziggy Stardust" bought in 1972; both of these vinyls have had literally hundreds of hours of play ranging from 1970's portable type record players right through the range of different turntables to my current Debut Carbon II. In each case the vinyl sounded much clearer and the noise levels were much lower. I then tried the headphones through the Duo amp and the sound was superb. I tried using Bowers & Wilkins P7 and PX headphones - both sonically great headphones. I was very pleased with the performance. My TV runs through the CXNv2 and the CXA80, but now I can listen to music while others are watching TV! Overall this is shaping up to be a great buy and will only sound better as it's run in. Would I recommend it? Most definitely!

Rated 5 out of 5 by from Simple and solid Very easy to set up and lifted the sound quite nicely. Comes with a grounding port too which is ideal.

Rated 5 out of 5 by from Quality stock and helpful staff I got this pre-amp for a top end pro-ject turntable. It's basically the best in the price range. It takes moving coil (MC) and moving magnet (MM) inputs and has a headphone output. That comes in really handy when listening to music late at night with headphones on as no need to fire up the amp. This is a very tidy, stylish and n-nonsense product. 10/10

Rated 4 out of 5 by from Great value good sound I bought this as stopgap while saving for a £1000+ phono stage. No longer sure I will bother with the more expensive one!

Rated 5 out of 5 by from Exceeded expectations on all levels. Initial impressions were that it looks beautiful and feels SOLID. Love the headphone option. Sonically it is so much of an improvement on my NAD PP3, Edwards Audio Apprentice and various (Sony ES and NAD) built in phono stages it isn't worth a detailed comparison: EVERTHING is more natural, more detailed and alive. Yes, it cost more than my other units, but it feels like a steal! I would add a video if I had a decent camera. For most vinyl players this is all you will ever need. I have decided to keep my Project Xpression II/Ortofon OM30/Speed Box II combo because I am smitten with the way the Duo makes it sound. My NAD C162/370 and old KEFs have also been reborn.

Rated 5 out of 5 by from terrific phono amplified I have a Linn LP12, fitted with an Akito arm and using a Lingo power supply. I wasnt sure if this would be good enough for my turntable but decided to change my phono amp after seeing the What HiFi review and am glad i did. Its a terrific phono amp and with plenty of punch. To have the headphone ouitlet is a real bonus. Ddefinitely a nother great Cambridge product.
