R720 at £200 all the way for me if you want to go down that route. I'd still go for the amp though
I had Monitor Audio BR2's in a second system a bit back and was really impressed with them.
Tysons are just up the road from me and I've bought loads of stuff from them. Very good firm.
edit: didn't realise you were posting at the same time - I was comparing the R720 to the dinky little thing. BK are supposed to be spot on but not heard them
