”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.

Give your system a double whammy upgrade, with the Cambridge Audio Duo.

Rated 2 out of 5 by from Not for me Read the reviews and thought I would give this a go but the WhatHiFi review was correct that it lacked punch. After a short go with it opted to return it and gone back to my Project pre amp.

Rated 5 out of 5 by from Perfect Apparently the only device currently on the market that can separately connect a MC and a MM cartridge, and provide a switch on the front to select one or the other.

Rated 5 out of 5 by from Cambridge Alva Duo This is a brilliant piece of kit. I gave up hope that I could link my old 1970’s high quality turntable until I found the ALVA DUO - it is a great design very simple to use and wonderful sound quality. The added bonus of the headphone socket is a good touch

Rated 5 out of 5 by from Outstanding piece of kit has transformed my sound I've just added a Cambridge audio duo phono preamp to my setup and it's transformed my vinyl sound. I didn't need a preamp as my project deck has one built in but I got the duo as it has a headphone socket which means I can now plug in my Bluetooth streamer and listen on headphones while my better half is watching tv! Up until this I could only listen to vinyl while the TV was off or she was out! It's not just a preamp though it actively cleans up the sound and reduces rumble and pops and scratches. Outstanding piece of kit for serious vinyl listeners! Got mine in the black Friday sales £100 knocked off so very happy!
