”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 5 out of 5 by from Clear detailed sound with very low noise floor! I was looking for a fairly affordable phono stage that still gives great results. And all the internet hype led me to the Schiit Mani. A solid perfomer for sure, but plagued by constant issues of RFI, constant hum/ buzz and all of that with a high quality linear power supply... My turntable doesn't provide a ground point as its internally grounded, that might have played some part in the whole experience as I can't connect a ground wire from the tt to the phono preamp. So I kept looking for a new phono preamp, something that still has the nice level of detail and dynamics of the Schiit Mani but is also quiet until I drop the needle on the record. And sure enough the Cambirdge Audio Duo is it, and then some! I was hesitant to go for this model as there's not many reviews on the web, but it was the right choice. Bass is as punchy and deep as you'd want it to be, very detailed and quick. Mid-range has plenty of air, with precise instrument separation and placement. The highs are energetic but not fatiguing and the whole sound is very dynamic, overall amazing. At first I wasn't sure on its sound versus the Schiit Mani as it seemed a bit laid back, too mellow. Few weeks of breaking it in and now its just as enjoyable as the Mani if not more! This is a truly audiophile designed equipment, it doesn't add any coloration to your music, just lets it sound its best. The best thing about it... noise floor is incredibly low! Only the slightest buzz at the volume levels I will go deaf at and only if I put my ear right against the speaker, otherwise black silence until the record starts. An extra bonus is that it supports MC cartridges if I ever upgrade, oh yes and a very decent headphone amplifier! Highly recommended phono stage!

Rated 5 out of 5 by from Small box smooth detailed sound I was looking for a bargain and found one 5 stars at £250. I paid £200. The improvement to the sound quality I was use to was unbelievable my main reason for this phono stage was being able to plug it into the auxiliary on my valve amp and the ability to put a moving coil cartridge on in the future at a budget price. Do not wait buy one today. P s it dose not sound like it's budget price.

Rated 5 out of 5 by from So pleased. I was reasonably happy with a cheapish preamp for my aged Rega Planar 3 deck but listening with headphones was complicated with my set up. I decided on the Cambridge Duo primarily for the headphone amp rather than add yet another plug for a separate headphone amp and the existing preamp. I am so pleased I chose the Duo even though the price was a bit high for my budget. My vinyl has gained a new life, so much more detail and range. Listening with headphones is wonderful. A very neutral (bass v treble) and detailed experience. Sadly it has exposed the weakness of the rest of my system and I now need to review my main amp and speakers HiFi is a dreadful disease!!

Rated 5 out of 5 by from Expansive soundstage, great detail ... buy one! This is one of those purchases that I wish I’d made ages ago.. lifted the sound of my turntable to dizzying new heights... beautiful, wide soundstage, exquisite timing and drags detail I’ve not heard before out of my records. Add to this I ordered online the Sunday before Christmas (Preston didn’t have one in stock) and it was here at 10.30am the next day.

Rated 5 out of 5 by from Enjoying vinyl again with a great pre amp. I bough this a few weeks ago on the advice of the instore staff at Swiss Cottage who were very knowledgeable and helpful. It's definitely given my vinyl a boost. Loving it!

Rated 5 out of 5 by from Great piece of kit Recently purchased this as an upgrade from the old Cambridge Audio 640p (which I was also very impressed by) and it sounds fantastic! A lot more open and precise the the previous model and my partner loves the fact it has a dedicated headphone output. Just need to save my pocket money for a high end set of headphones! Many thanks to Steve in the Reading branch for his help and the cup of tea
