I have the Cambridge Audio Azur 540R receiver. It is a nice little unit. Certainly different from the more common brands. I bought it for its video switching ability primarily but soon it may be headed upstairs for a bedroom system or for sale. I haven't yet decided.
It does not power my main speakers, Tannoy Definition 700s. They are powered by an Anthem amp, but the Cambridge acts as the preamp section.
All in all it has been a good unit.
