Cambridge Audio Azur 851A


For scale and power, not to mention build and style, the Azur 851A is hard to beat

Solidly built, smartly turned out ; Clear display ; Array of inputs ; Big, powerful sound

Lacks organisation and poise when really pushed

But if it’s room-filling sound with impressive clarity, weight and bags of power, then the Cambridge Audio Azur 851A should be on your list.

Effortless Bass, Sonic Separation, Audiophile Heaven!


So you're reading this review for one reason, and one reason alone. Q: Should I part with £1200, is the 851A really worth it? The short answer is most definitely yes!! I partnered the 851A with the 851N, and boy was I blown away. As soon as you turn...

Find your feature


No problems with the output quality, obviously very good. Much vaunted features are a tad more difficult to appreciate, unless you either have a Richer Sounds expert on hand all day, or can spend many hours experimenting/rambling in menus. May be a...

A fine amplifier


Following an inheritance I had decided to spruce up my hifi. First to go was the amp, to be replaced by The Cambridge Audio Azur 851A. With its array of analogue inputs both balanced and unbalanced and record output this suited my purpose and the...

excellent build quality coupled with sound quality that more than justifies the purchase price


Slowly getting round to updating my old system & wanted a good amp. Read the reviews on this unit & arranged a demo at the Norwich branch (top guys there). It was delivered early the following week. Really impressed by the build quality & the...

This amp produces a great sound


I bought the amp to power my digital library from my PC on my desk. I paired it up with Focal bookshelf speakers and cambridge audio mini speakers behind me. The combo produces excellent quality audio at all volumes and does not lose quality at lower...

Clean unforced sound capable of incredable resolution without ever sounding harsh


Purchased this amp on the merit of owning it's predecessor (840a) for 7yrs,which now resides in a bedroom system. The highly respected and straight talking musician and hifi reviewer Richard Black (hifi choice) helped draw my attention to Cambridge...

Cambridge Azur 851A Magic


OK ...I allowed four weeks before writing this review to allow the amp to break-in. This is a very fine 2 channel integrated amp and very quiet, it was matched with B&W Cm9's with the transport of choice being an OPPO 105 utilising balanced XLR...

Crisp, rich and tight whilst delivering a nicely detailed and musical experience. Very good value for price
