The Cambridge Audio Azur 640A v2 is a very good value. I would tend toward the Cambridge Audio as it has more power and sonic characteristics not that different than a Rotel. However, if using a turntable the Rotel has a decent phono input whereas you would need a phono stage for the Cambridge Audio.

Rotel and B&W have some common ownership and B&W speakers are voiced with Rotel electronics and Rotel electronics is voiced with B&W loud speakers. It's a guaranteed excellent match. In many respects they were made for eachother.

I cannot speak to the amp but I use a Rotel CD for a transport and am very happy with it.
