Richer Sounds exclusive model.

When combined with the equally impressive 851E or 851D, the Cambridge Audio 851W power amplifier is quite simply the best sounding Cambridge Audio amplifier ever.


Massive power for effortless sound, whatever the speakers

Take a look at the figures and it soon becomes clear that, when it comes to power, the 851W isn't going to take any prisoners! With a genuine 200 watts per channel at 8 ohms the 851W has a cast iron grip on any speaker, no matter how difficult the load. With a 4 ohm load this figure increase to 350 watts per channel. Should you choose to use two 851Ws in bridged mono mode, these outputs increase to a jaw-dropping 500 (8 ohms) or 800 (4 ohms) watts per channel.

Twin toroidal transformers
At its heart, the 851W is powered by twin toroidal power supplies. Separate transformers for the power amplification and input ensure the audio performance is unaffected by large current requirements caused by powerful and dynamic music from current hungry speakers. What this means in terms of sound quality is deep, effortless bass with thunderous dynamics on tap.

Terrapin impedance buffering modules for enhanced detail
Cambridge Audio's own Terrapin impedance buffering modules replace the more commonly used op-amps for a further leap in audio quality. Terrapin impedance buffering modules separate amplifier and signal impedance, delivering an even and consistent sound with enhanced separation and imaging.

Unique Class-XD Amplifier
What makes this amplifier extra special is the Class XD amplification. Technically speaking, this combines the best qualities of Class A amplification - smoothness and realism - with the best from Class AB - power and control, without the disadvantages inherent with both designs. What this means to the listener is a smooth, yet detailed sound quality with the ability to drive almost any speaker from its substantial power output.

Full metal casing with 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, meaning that it won't resonate unhelpfully. The thick aluminium front panel looks the part and also acts as a shield against electrical interference from sources such as dimmers and RF devices. All these details combine to create an amplifier that not only looks stylish but also offers exceptional resistance to both mechanical and electrical interference.

For an amplifier with power to spare yet the finesse to impress, the Cambridge Audio 851W is in a league of its own.

Rated 5 out of 5 by from Azur 851 Power Amp. I am really pleased with the power amp, it was very good straight out of the box but is even better now that it is " run in". It has power to spare but also has the ability to reveal all the subtle detail in all kinds of music. It is what I would describe as very musical and makes listening a pleasure.

Rated 5 out of 5 by from Hugely Impressed I bought three of these amps to make up a surround sound system in my music room. Two drive the rears and one drives the center all in bridged mono mode. The rears are connected to a pair of Kef R11’s and I’m using the balanced output of a Stream Magic to provide a source for running in the amps and speakers. Both the speakers and amps have proved to be way better than I had expected. Detail and musicality are excellent. Imagining and depth are very good and the room, around 42 square metres with high ceiling, is easily filled with sound. As for sheer volume of sound, it’s just endless.

Rated 5 out of 5 by from Stunning looking and exceptional build I bought an 851W 6 months or so previously and was so impressed I decided to buy another and bridge them, wow....sounds superb with so much power, but with incredible musicality, very happy customer

Rated 5 out of 5 by from Perfect powerhouse This amplifier is simply superb. It has a powerful, clean sound and can easily drive large or challenging speakers. I got a real step up in sound quality when I plugged it in, much firmer bass and wider soundstage. Easily drives my large 4 Ohm floorstanders plenty left in the tank. You could get two of them and bridge them into monoblocks but I'd be worried that you'd cause structural damage to your house. Easy to set up, works well with pretty much any equipment and sounds fantastic. I'd have happily paid twice as much to be honest.
