Cambridge Audio’s Azur 650R A/V receiver has been built, I think, with old-school audio purist in mind. Obviously, the 650R was designed with the thought that it would be used in conjunction with very high-quality video/audio source components. Unlike some AVRs, then, the Cambridge does not seek to modify or otherwise embellish upon the signals it is fed. Rather, it strives to reproduce those input signals with as much accuracy and purity as possible—a job it does very, very well.
While the 650R does not offer features that have become commonplace in competing AVRs, such as room/speaker EQ systems or extensive onboard video processing functions, it offers easy to use, noise free video switching and transcoding functions, plus superb core sound quality, which is something that never goes out of fashion.
