”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 5 out of 5 by from Audio Duo: very fine product. I purchased this because there are a number of different ways in which I can use it. As a headphone amplifier I think it delivers very good sound, although I do not possess particularly expensive headphones. However, where the Audio Duo really scored in my view is, as was suggested in the advertising, when instead of using the phono socket of my (Marantz, two-channel) amplifier I instead used the Cambridge phono section and an auxiliary input (line input). The difference in sound was - to my ear - equivalent to a cartridge upgrade. The image definition was improved, and the sound was 'tighter', albeit not compromised in any way. (I have been in the classical music business for 40 years, so have long cared about sound reproduction. I also use a Pro-Ject RCM on my LPs and the Hi-Fi news reference LP for cartridge setup: all my vinyl dates from the 1970s and early 1980s.) Although I use only moving magnet cartridges with my two (Dual) turntables, the Audio Duo additionally gives me the option of upgrading to moving coil should I wish to. Finally, my excellent Denon 5-channel amplifier does not have a phono input, so I could if I choose use the Audio Duo to connect a turntable to this. Overall I would recommend the Cambridge Audio Duo as a thoroughly worthwhile, versatile product which gives excellent results.

Rated 5 out of 5 by from Quality Piece of Kit. Lovely Sound and Good Value After narrowing my search down to this item and the also highly rated Rega Fono MM MK5, I bought both and listened to them back to back. To my ears there wasn’t much in it however the Cambridge Audio Duo sounded cleaner, warmer and overall just better than the Rega Fono. Another deciding factor was the look and feel of both items. To me the Rega looked and felt almost as if it was produced on a 3D printer and didn’t look or feel like a quality item. The Cambridge on the other hand looks and feels so much better than the Rega. Of the two and probably any other phono box around the same price, I can highly recommend the Cambridge Audio Duo. It’s even better value if you can buy it using the VIP member discount like I did. Overall I’m very happy with this purchase and the service provided from Richer Sounds.

Rated 5 out of 5 by from Great product, perfect for what I needed. Popped in the Romford branch just for a bit of advice on what I needed. Very helpful and they had the item I needed.

Rated 5 out of 5 by from Excellent Bought to replace Pro-Ject Phono Box MM as I was getting a background hum. This product has completely eliminated the hum and improved the overall sound quality of my vinyl. Would highly recommend this item.

Rated 5 out of 5 by from Best in class to my ears Simply, in my system and with my ears, this is a better phono pre-amp than the generally accepted class leader (Rega). It seems cleaner and clearer through the midband and has a more natural balance across the frequency spectrum. Most tellingly, I currently have both and it is the Duo that I choose to use. My only gripe is that I would have preferred just a little more gain but this is common to most phono pre-amps I have used. I am sure this is very system and particularly cartridge dependant - Nagaoka MP300 in my case. I haven't used the moving coil input so cannot comment on that. The headphone output is good and I would be quite happy to use it but I rarely use 'phones. So: an excellent well balanced sounding pre-amp that feels well built. I would recommend it strongly even if you don't need the headphone socket or the MC input though the latter may be useful at some time.
