Integrated Amplifier

Taking cues from the award-winning 651A amplifier, this slimline yet powerful amplifier features 45 watts of power per channel, a USB audio input, and a front facing 3.5mm jack for easily connecting iPods and MP3 players. At this price point it's unbeatable.


The 351As minimalistic all metal casework was chosen not just for its aesthetics, but because of the low-resonance properties and the excellent stable foundation for the electronics it offers. The brushed aluminium front panel is an object in simplicity and just features volume, power, source, and tone controls.

This is just one example of the no compromise attention-to-detail which places the 351A head and shoulders above its competition in terms of sound quality.

Digital Input

The 351A offers a wide range of inputs so you can connect and enhance all your entertainment devices. Most importantly, we've developed a brand new USB audio input so you can directly connect your Mac or PC. A Burr Brown DAC (digital to analogue converter) takes the digital audio signal from your computer, bypassing its basic soundcard, and takes care of the delicate digital to analogue conversion process inside the amplifier. So for listening to iTunes and streaming services you can connect your computer to the 351A and use it as your primary audio source with CD quality results!

iPod Integration

iPods and MP3 players can be connected to the 351A via a dedicated 3.5mm jack on the front panel. In addition, our supplied remote features iPod command codes enabling you to control your iPad, iPhone or iPod when it’s connected to a suitable dock such as one from our id range


5 gold plated audio connections are also available for all of your other entertainment sources like CD players, tuners, network players and even your TV. The gold plating provides a corrosion free and highly electrically conductive surface for a perfect connection.


The 351A features a heavyweight toroidal transformer, a premium component chosen for its ability to offer huge power reserves, excellent bass response, and rich musical reproduction across the volume range. We always concentrate on the quality of the key components rather than adding unnecessary functions or connections. This ensures that we can offer an undiluted audio performance.

We allow you to boost your audio performance even further with the Direct switch which disables the 351As tone controls to give the shortest possible signal path.

What Hi-Fi Sound and Vision (GB, )

"The two Cambridges make a formidable pairing: the 351A offers precision, while the 351C revels in the subtleties."


Gramophone (GB, )

"This is a rather special combination from Cambridge Audio and all credit is due to its designers for delivering so much music at so reasonable a price."


On Top Audio (FR, )

"...un excellent départ pour une chaîne hifi digne de ce nom."
