I just heard these side by side today, and was really surprised, the B&W just plain sounded better, the KEF sounded like it had a veil over it. Now to be fair the R11's were not placed ideally, the B&W were in a better spot, but I do not think that would account for the difference. And I want to add, I have not been a fan of B&W , and was considering the KEF R7's, now I have some thinking to do:)
KEF R11 vs B&W 702 vs Golden Ear Triton 1.R vs?
Looking for speakers in the $5000-$6000 pair range. These three are well rated and available locally
