Can a set of Ls50 metas surpass or equal a set of Kef blade metas with subwoofers

Agree with @vinnydabully.   Ls 50’metas are a benchmark setting product and every hifi enthusiast should hear a pair. 

subs don't really fill in the midbass and that's a tall order for the little ls50's. I have a local KEF dealer and before the original ls50 price dropped to $1100 he was pretty confident the R3 was the better speaker for the money because the woofer helped fill out the bass. Now both those speakers retail for less than the sales tax on a pair of Blades so it would be nice. I think if I still got high a pair of R3's and a k62 would be more than enough to keep me engaged.

On side note. My KC62 had a design flaw in the batch it was part of (wireless transmission). KEF asked me to send it back to them. When it came back to me it did not work. The shipping packaging was damaged, but the unit was also packed in the wrong way.

I did not make a big stink about it and was just going to get it fixed myself at George Meyer AV in Los Angeles. KEF stepped up and is sending me a new sub. 

It's common knowledge that no speaker does everything... l just wanted to Say that Paul McGowan CEO of PS Audio, who can have whatever he wants chooses a pair of LS50's with a sub for his personal home for general listening...that alone means something 

I think John Atkinson from Stereophile also uses the LS50 as his main speaker. I was surprised at that.

I replaced a pair of LS50 Metas, UltraRendu, Ayre DAC, preamp. and amp with a LS50 Wireless II to declutter the living room.  Both speakers are Metas so I assume they are equivalent.  I continue to use a pair of KC62 subs,  The LS50 Metas are boxed up, but I may keep them as back up.
