”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 Great sound, good MC gain Bought this to replace a CP2 because of the extra 5db gain for MC cartridges. I have an Ortofon Quintet Blue on my Pro-ject TT, and I had found myself having to turn my CXA80 up higher than I would like on some recordings, especially Classical. This makes all the difference. The sound is very similar, very good, smooth and dynamic. Not such good value, an extra £100 for a headphone stage I don't need and probably wont use. Still good value @ 250 notes, though. One difference with the CP2 is the internal power supply. I had a good quality external power supply on the CP2 which made for a more solid sound with better bass. I have changed the mains cable for a shielded one, which brings greater clarity and detail. Overall a great sounding and good value phono stage, with better gain than its predecessor for MC cartridges.

Rated 5 out of 5 by from Perfect product I called the customer service line for advice first and foremost, being somewhat audio amateur, I beyond happy with the attentive patient service I received. I ended up being recommended the perfect piece of audio kit for my situation an was never felt I was being coerced into buying something that was too expensive or additional that I simply wouldn’t need. The whole process was extremely streamlined and the delivery was exceptionally prompt.

Rated 5 out of 5 by from Great pre-amp I needed a pre-amp to connect my phono deck to the hi-fi and I placed an order online. The very next day it was delivered to my door.

Rated 5 out of 5 by from Excellent Cambridge Quality Having never used a preamp before I was not sure what to expect. I have gone back to vinyl which has necessitated an overhaul of my system which included an audiophile pair of headphones. Although my Fluance deck had an integrated preamp I wanted more and invested in the Cambridge Audio Duo. In the words of the Richer Sounds manager the difference will be “Night & Day” and it was. Excellent pure sound from my Vinyls.

Rated 5 out of 5 by from Cambridge Audio Duo - Exceeded Expectations I've been suffering with a poor pre-amp for years, so it is with no hint of exaggeration that the addition to my set-up of the Cambridge Audio Duo really transformed my listening experience. It's absolutely fantastic. There's no background noise, and the depth it gives to the sound is wonderful.
