In that case I think your choice of the KEF is great. It sounds similar to the Vivids to me. I have heard both a lot.
I was looking at USAuidomart yesterday for some KEF's because of some anxiety I had with my 'new' speakers (resolved today). There were a lot of KEF Blades going for $12K,which is still a lot more than a demo Ref 3. However, the Blade is a big jump from the Ref 3.
