KEF Reference 5 vs. B&W 802 D3 speakers - which one better? your knowledges & opinions

I somewhat casually listened to a head-to-head of these two speakers about 18 months ago. I believe the electronics were Anthem separates. Unfortunately, I don’t have a good recollection of the demo, except that I wasn’t floored by either speaker (perhaps that was due to the relatively lower quality electronics, and the room wasn’t great either). I didn’t have a strong preference for one over the other - but they do sound very different, that’s for sure. Neither speaker really my cup of tea, I guess (personal preference). Sorry not what you wanted to hear and probably not helpful at all. For what it’s worth, the salesmen at the dealership all seemed to prefer the Kef (so maybe that is a little bit of useful info).

Now that you mention that, I think when I heard the Kef Ref 5 vs the B&W that the Kef's were mentioned as having recently arrived at the dealer (like a week ago), and so were probably not fully broken in when I heard them.
