This page is intended to demonstrate the incredible value of our 6 Year Supercare. Under recent legislation, we are obliged to point out that you obviously do not need to purchase an extended warranty at the same time you purchase your electrical goods and are entitled to shop around. We have been encouraging our customers to do just that for years because, not only are our prices significantly cheaper than our competitors, but just look at what else we include:

Free loan machine (only if taken back to store)
Should you encounter a problem, just ask and you'll be provided with a unit to ensure you're not without music whilst your equipment is being fixed.

Like for like machine if unit is unrepairable
If, for any reason, we are unable to repair your unit, we'll replace it. Naturally, models do change so, while we can't guarantee that it will be the same model, we do guarantee that it will have equivalent specifications.

Free routine service / Maintenance checks
have your unit serviced as often as you wish, free of charge, during the 6 year period. (Normally excluded from extended guarantees).

45 day cooling off period
If you're not happy with our 6 Year Supercare package just ask for a full refund - no questions asked. After 45 days, providing no claim has been made, you can also terminate the agreement and receive a pro-rata refund.

If you use the policy in the 6 years, you'll have saved yourself tens and perhaps hundreds of pounds. If you don't use it...IT WON'T COST YOU A THING!*

* Simply return your unused Supercare policy within one month of the expiration date, and we'll refund the price of your warranty.

The highest quality CD performance

If you've a treasured collection of CDs and are keen to keep increasing your collection, the Cambridge Audio 851C will get the very best out of the format. At the heart of the 851C is a 32-bit Analog Devices Black Fin DSP (Digital Signal Processor). This feeds two of its AD1955 24-bit DACs in dual differential formation, each handling just one channel for excellent stereo imaging. What you hear is an exceptionally unforced, natural sound. Instruments and vocals 'breath' with emotion and depth, the sound has colour, texture and fluidity for an uncanny a sense of realism.

AFT2 audio upsampling
The 851C also has an Anagram Technologies AFT2 24 bit/384 kHz up-sampling circuit. Up-sampling conventional CDs 'stretches' the format to give the highest resolution possible. It also aids standard 24-bit/192kHz recordings with a faster sampling rate for less jitter. Up-sampling gives a smoother, more relaxed sound quality with added detail. You'll also notice enhanced depth and a more natural quality without the 'edge' that can afflict digital music. You'll hear every detail, including the odd cough, squeaky chair and flutter of sheet music; in short, it's like being there for real!

Tailored sound
As we all prefer slightly different nuances of sound quality, the 851C comes with Cambridge Audio's triple filter system. Select from Linear Phase, Minimal Phase or Steep modes and you can subtly alter the sound quality. You might even find certain types of music sound better with a particular filter engaged.

A DAC for all your digital sources
The Cambridge Audio 851C not only has digital outputs but also comes with four digital inputs. What this means is that you can connect up sources via a choice of optical/coaxial for inputs 1 and 2 and XLR or USB. So pretty much any digital source with a digital output can have its sound improved by being connected into the 851C.

Digital pre-amp functionality
The Cambridge Audio 851C is not just a top quality CD player and DAC; it's also an impressive digital pre-amplifier too! Use digital inputs 1 and 2 to connect up your Blu-ray player, games console or any other source with a digital output and use the pre-amp to select the source and alter the volume/balance. Connect your PC or media device by USB, as well. Once processed, the signal is ready to go straight into a power amp or active speakers - making for a, very high quality minimalist system.

Extensive damping
Using a full metal casing with rounded edges, doesn't just look and feel good, it helps the sound, too. The case is rigid and well damped, so it won't resonant unhelpfully. The thick aluminium front panel acts as a shield against electrical interference from sources such as dimmers and RF devices. All these details combine to create a hi-fi component that not only looks stylish but also offers exceptional resistance to both mechanical and electrical interference.

Reinvigorate not just your entire CD collection but also all your digital sources - the Cambridge Audio 851C is a powerful tonic for a tired system.

Rated 5 out of 5 by 2 reviewers.
Rated 5 out of 5 by Detailed high quality sound The clarity and detail that this CD player reveals was apparent when I first heard it in the shop demo room. It has really added to the overall sound of my hifi system. 31 October 2015
Rated 5 out of 5 by Huge Step Up From 840C System 840A with Mission 773e with QED Revelation Cables and Silver Anniversary Jumpers. My 840C died so the only like for like replacement was the 851C. When I collected it from the Sheffield store, the Manager, Stuart said that it would "blow me away". I was a little sceptical, and on first listening I was a little underwhelmed, but after I had burned it in I realised that he wasn't kidding. It feels that I have bought an entire new CD collection, on each one I am hearing things that I have never heard before. I have also hooked up my SKY HD Box up to the 851C with an optical interconnect and the audio is so much better that it was with the 840C. The soundstage is wide and detailed, and less laid back than the 840C was, more like sitting in the front row of a concert than at the back of the hall. Bass response is also fuller yet more detailed. Speaker positioning is also far less sensitive to produce a great soundstage. The 851C has raised the bar by a good margin. 22 May 2015
