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


I'm considering buying KEF Reference 5 or B&W 802 D3 speakers. I currently have McIntosh MC2152 power amp and C70 for preamp. Which one of these set of speakers will give me the best sounds. Please share and enlightened me as much as possible.  No recommendation for other speakers.  Tell me which one is better sounding.  Much appreciated.

I’ve experimented with the bass ports. Right now, I’m using four long ones and I’m pretty happy with the results. I think this is very system and room dependent so your preference may be different. You got a 33% discount on speakers that usually aren’t discounted.  I’d say that’s a good deal. But only if you like them. Don’t get buyer’s remorse...they haven’t even arrived yet.  
Congrats from another KEF Ref owner (3’s in my case).  I, too, compared the KEFs against the B&Ws and while I really respect the engineering prowess behind B&W, I greatly preferred the KEFs. I was also considering Sonus Faber Olympica 3s, (very different sound, but I like classical music and some jazz and they’re easy on the ears - and very easy on the eyes)), but again preferred the KEFs.  

FWIW - I had a chance to compare the KEF Ref 3s against the KEF Blade 2s using the exact same system and cables - we just moved the speaker cables from one to the other.  Yes, the Blades were better, but they were a lot closer than you might expect considering the Blades 2s are 2x the price. Let your Ref 5s fully break in and run them with decent source and electronics and I think you’ll find you enjoy them very much.  
@fast does that longer tubes give u more bass?? 
someone told me they got it for 11,000 euros.  To be honest, I’m already feeling buyer remorse because someone said not much of a difference of sound improvement coming from the R900.  What do u think?? 
@mgrif104 thanks for your information.   I was contemplating on which speakers to buy and i dont know if i made the right decision by choosing Kef Reference 5 over the B&W 802D3.  Its my first expensive speaker and i want to get it right without regret later.  My equipments are McIntosh MC2152 (tube 150 watts per channel) and C70 (All tubes preamp) Cambridge Audio Streamer/DAC Azur851n.   I’m already feeling buyer remorse because someone said coming from my R900 wont give me much of a sound improvement and the price I got it at $14k is couple thousand higher.   What do you think? These people’s opinions makes me feel buyer remorse. 
kentrent: you need to chill out!  This is supposed to be fun. You should be happy that you made a decision and also got a big discount. The euro price, assuming it was for a European purchase, is irrelevant to you since you would have to pay shipping and customs, and probably wouldn’t get a US warranty. Be excited about getting some of the best speakers available and looki forward to many years of enjoyment.
