I've pretty much made up my mind that I want to audition the AVR 400 based on reviews and aesthetics. But I've googled and googled and can't find any recommendations for suitable speakers, either specific models, or the price I should be spending. I do like the idea of the new B&W MT60-D, purely for space saving, but perhaps the B&W 683 theatre would blow them out of the water? I will of course demo before I buy, but first I need a list to demo! Ideas or experience please?
