Kentrent: while it’s true that the R900 is a very good speaker and its tonal balance is similar to the Ref 5, there is indeed a significant difference between the two. I have heard the Ref 3s against the R900s (they didn’t have the Ref 5s but it stands to reason the 3 and 5s are similar tonally and in resolution). While they Reference and R series have a similar “voice”, the Reference offered significant improvements in resolution (detail), and clarity that was very easy to hear in comparison.
Speaking with a KEF representative and reading some of their literature on the Reference series, it would appear that some of the improvement in clarity is due to a significantly better coincident driver and crossover for the midrange and tweeter, and some is due to better (non resonant) cabinet construction. KEF are thoughtfully engineered speakers - you get what you pay for at each price point.
I would actually suggest the gap is much wider in performance between the Reference series and the R series than it is between the Blade and the reference. I have done this exact comparison. The Blade is 2x the reference in price. As in all things - diminishing returns as you move up.
Make sure you let them break in. If you don’t love them after a few hundred hours, then you can consider what next. But, I’d politely suggest it won’t be the speakers that will be your weak link.
My $.02.
