Has anybody been able to make a comparison of these B&W speakers? Here (in Finland) they cost the same - excluding the stands needed for the nautilus pair. I'm afraid I can't compare them locally. I'm suspecting that with a decent sub (Velodyne SPL-1200), the 805 pair would be a better choice. Do you agree? How about 705's? The speakers would be used in an about 4 x 7 m room, two walls made of concrete. They would be run with a Denon AVR-3803. I know many people think that it's not enough for speakers like this. However, I can't currently use very high volumes and when I finally manage to get a dedicated AV room, I'll probably get a better multi channel amp (like a Rotel RMB-1075).
