"Extraordinary array of features; refined and revealing sound that puts musicians in the room... Smooth, svelte sounding amp with power."Hi-Fi Choice magazine.

Class XD amplifier design

What makes this amplifier very special is the Class XD amplification. This combines the best qualities of Class A amplification - smoothness and realism - with the best from Class B - power and control, without the disadvantages inherent with many Class AB designs. What you'll hear is a smooth, yet detailed sound quality with the ability to drive almost any speaker and a substantial power output.

Massive toroidal power supply
At its heart, the 851A is powered by a massive toroidal power supply, which accounts for a third of its the weight. Not surprisingly the 851A has a monster power output: 2 x 120W into an 8 ohms and an awesome 2 x 200 watts into a 4 ohms. What this means in terms of sound quality is deep, effortless bass. Furthermore, such is the control and current that the 851A handles tricky dynamic sections, such as the sweep of a full orchestra with consummate ease.

Power with control
The 851A can do subtle, too. By using a separate toroidal power supply for the pre-amp section, the 851A ensures that pre-amplified signals arrive at the power amp stage in the best condition possible and so are brimming with subtle detail. Short of having a separate pre/power amp combo, this separate power supply is the next best thing.

Dual mono configuration
With separate taps for the left and right channel from the power supply, and separate left and right amplifier circuits, the 851A is a true dual mono amplifier. By having separate circuits for the left and right channels, each channel has its own, distortion-free feed. This brings about greater separation between instruments, greater width of sound and enhanced realism.

Plenty of connections
With no fewer than eight audio inputs, the 851A is capable enough to handle even the most complex of systems. XLR balanced connections offer a professional-grade connection with compatible equipment, such as the 851C CD player and Stream Magic 6 network player. Fixed level inputs make it easy to use the Azur 851A as the front amplification as part of a home cinema system, while the large display can be programmed to name your sources, so that, for example, the PlayStation 3 input is labeled, 'PS3' rather than 'Aux 3'.

Full metal casing
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 resonance 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.

To experience music more vividly than ever before, the Cambridge Audio Azur 851A provides your front row seat.

Rated 5 out of 5 by from Great build, great sound and features Bought the Azur 851A amp recently to go with my Focal Aria speakers and my Azur 851N streamer. The streamer sounds amazing but coupled with the amp and the Focals it is outrageous. The amp has power and drive and punch but also can deliver smooth relaxed music when required. It can do it all. The main thing i notice is the detail and the sweet treble without any hint of harshness despite my speakers having metal tweeters. Songs i have known for 30 years sound like i am listening to them for the first time as i can hear things i have never heard before. I demoed a Naim Nait XS2 recently and the Azur 851A is superior in my opinion. The Naim, while excellent, does not have the insight or detail of the Azur and the Azur matches it for drive and punch. Very pleased with this amp and it will be at the heart of my system for the next ten years.

Rated 3 out of 5 by from Fantastic quality and sound but The Cambridge Audio Azur 851A is a very talented amplifier, the build quality is excellent, but the sound quality is what makes it stand out, it is very musical and a pleasure to listen to, it doesn't pull you in, you get into the music of your own accord, it's such a wonderful place to be, I found that it handles vinyl slightly better than CD (but you have to compare them side by side to notice this), perhaps I need a better CD transport, the Cambridge Audio Azur 851C is very tempting. However there is the small matter of the but in the title and only 3 stars, I have speakers that are rated at 100 Watts each and very easy to drive, the 851A has 120 Watts per channel so enough power, but I have to turn the volume to 80% before the amp starts to give anything meaningful back, I didn't want to push it further as I don't want to ruin my speakers, but the 851A just runs out of meaningful power, it really needs to be partnered with a power amp to get out of it what is in there, the detail and music are fantastic but the lacklustre punch is killing what is something very special

Rated 3 out of 5 by from Good to a point but limited power I bought this amp a year or so ago and have since traded it in else where in favour of a pre and power amp combination which I am delighted with. Whilst the a851a amp is well made and capable of some great imaging and tones, the advertised power just never delivered for me. Far from it in fact. I always though it was very quiet given the advertised muscle. Cranking it right up, I felt that the xd technology just fell apart and switched into a very harsh tone where the detail just feel out. This was at a very specific volume level too. Adding a phono stage was tricky as I had to turn it right up to passed 60 / 70% just to get the air moving... Whilst power in Watts can be misleading, the gain on the pre amp was is set way way too low, it simply doesn't make enough noise. My speakers need a little more power than average but nothing that should stress the figures stated. Anyhow, I wanted to love this amp and it ireally is capable of tremendous sounds but I was for ever wanting more from it and it never mustered up what I wanted from it. I have to say that team at richer sounds are brilliant and cannot recommend them more. The product missed the mark here by a whisker and when you spend a £1000 +++++ on an amp that is not good enough.

Rated 5 out of 5 by from Brilliant All Round Performer I purchased this amp a couple of weeks ago and I am totally over the moon with it. The sound quality is too die for especially when I am pairing it with the Cambridge 851N Network Player. I would not hesitate to recommend this amp to anyone looking for superior sound and build quality, and the other bonus is just how professional the Richer Sounds (Bromley) were when I was trying to decide, thanks very much guys.

Rated 5 out of 5 by from Great quality sound and build Wanted to upgrade my 650 azur, so I went for the 851A, and glad I did, this is an excellent amp both in terms of sound & build quality ( weigh 's a mighty 15 kg so be careful when moving it!.

Rated 4 out of 5 by from Early days I bought this to match the 851N media player with which I am so pleased. The 851A is equally well built and they look great together. Too early to offer useful feedback on sound quality but no regrets so far.
