7.1 HDMI AV Receiver
As TVs become impossibly thin - and sound quality gets even leaner - there's never been a better time for a home theatre system that sounds sensational but is also simple to use.
Music is at the heart of Cambridge Audio and this all new AV Receiver is designed to deliver sound that's in every way as epic as the picture quality from your movies, music and TV shows.
So, as well as all the latest processing features you'd expect, the 551R's ability to reproduce music with incredible richness and authority really separates it from the herd.
A staggering 110 Watts of power is achieved by combining Cambridge Audio's audio design expertise and the choicest selection of audiophile components.

"We used the Azur 551R with a number of albums from different genres. And what we could not believe was the overall tonality of this AV receiver"
"If you rarely want to do more than load a disc or tune a station and then sit back and enjoy, then the Cambridge very well might be your A/V receiver... My test bench results for Cambridge’s Azur 551R reflect outstanding performance on almost every test."
"Cambridge engineers put their efforts into the sound, which is, as I recall, the reason people used to get excited about hi-fis and home theaters."
