@output555 when I mentioned that the KEF weren't exciting enough for me at the time wasn't a remark about the high frequency. At the time I was looking for something with a bit more personal character if that makes sense. The R3 are just a very good all around bookshelf. I've compared them to their cheaper Q Meta line & there is a difference in sound. It's a more refined & mature sound. Objectively there isn't really any faults in the R3 Meta..being a bookshelf. A subwoofer really ties it all together.
So I didn't find them to be bright or dull. Now the room I listened to them mostly in has sidewalls 8 & 10 feet out. Before selling them I tried them in a bedroom with much closer sidewalls & I could hear an uptick in high frequency energy. Maybe that has something to do with certain people's opinion of them being bright-ish. I did love the fact that you can place them very close to the wall behind them without altering the clarity. I had them maybe 17 inches from back of speaker to wall..a good 30° off axis. Using REW this gave me a nice roll off up top..which is what I prefer. I do not like a bright or overly extended frequency response.
I think that the R3 is a safe speaker to buy. The objective measurements are extremely good. I wish I would have tried the Mofi but the next bookshelf that crossed my path ended up being a keeper. Regardless of me selling my KEF's they are a good bookshelf. You could do much worse. Good luck.
