I have a pair of Kef R1 Metas on order. I purchased these without an audition because I was so impressed with the sound when I auditioned a pair of KEF LS 50 Metas. As crazy as this sounds, the KEF LS 50s (in the room that I auditioned - small) were more engaging than my B&W 802 D3s in my home (which I have since sold- both home and B&Ws - I had a very voluminous space). Room acoustics does play a significant role, as I learned. I still love the sound of B&W, though!
As far as Focal, they are very bright to my ears. I have heard the Sopra 1 and all Kantas. Depending on your room size, a pair of LS 50s with dual subs would sound crazy good! I think the KEF R1 Metas with subs would be hard to beat. There is something magical that happens with the introduction of subs, albeit, I do love my bass.
You are in a difficult position because the KEF 3's are pricier than most of the speakers you mentioned. The only "dramatic improvement" would be an introduction of subs into the existing system, or to the speakers you mentioned. A dramatic improvement means spending a lot more $$$.
hi i already have nad m33
for which i payed 6000$ its purifi streaming amp, 200w per channel at 8ohm, i dont need/want wireless or speakers with integrated amps like ls ii, i want speakers which i can power from my amp like kef r3- i currently power kef r3 from the nad m33.
i also have dirac and many other things from nad...
i never heard from my entire life bowers and wilkinsons but 805 d4 is much very improved with diamond tweeter technology,
focal is with berylium tweeters etcs...
i also think bowers and wilkinsons hold great value ?
which is not true for kef and focal.
802 d3 is at least 1 generation behind 805 d4 series.
how about FOCAL UTOPIA DIABLO?
thats flagship speaker which you can compare with bowers and wilkinsons 800 series and focal reference series?
kanta and sopra are low end speakers...
i dont use currently sub but i have old jvc sub.
my kef r3 is non meta so not sure how much better is this meta,
also i think 805 d4 is much better speaker compared to r3 ,
all of these speakers are pricy 805 d4
focal diablo utopia kanta,sopra etcs..
