KEF Blade 2 as replacement for Reference 107/2

There is a very slight compromise in the Blade 2 and even Blade speaker in regards to the point where the bass/mids from the side firing drivers crosses in the UniQ mid driver. Its a small compromise gives in trade an optimized baffle shape that allows the Blade series to have an improved image and sound stage as compared to the Reference 5 model, which shares some similarities in driver complement.

Honestly, its not something your would really notice unless you carefully compared the two side by side. Either speaker is very well sorted out and you have to option to the Reference 5 if you so choose.

If you exclude the bass of the Blades (play something acoustic) and compare to the LS50 the Blades are still way better. The Blades disappear and give the best soundstage I have heard. It also has the largest sweet spot of any speaker I have heard. Compare the Wilson Alexa to a Blade and you will see the difference in sweet sport size.

The KEF Reference line is also very good. Not Blade level but the Uni-Q driver is also excellent on the Reference line. The lack of coherence on the Blades is a new one to me. Everyone’s ears are different, mine love the Blades.

I heard the older top of the line KEF model at a dealer and I was not that enamored. The Blades and LS50 I love.

Bass on rock is often just a loud bump between 120 to 180 Hz.

My 107/2s are driven by a Parasound JC 2 BP preamp and JC 1 monoblocks, LS50s by an Ayre KX-5 Twenty preamp and VX-5 Twenty amp.  I suppose either setup would be suitable for driving Blade 2s. 

Although I have no experience with the 107/2s, I do have a Pair of Blade 2's powered by a chord hugo 2 > c22 pre amp > 2x Mcintosh 275 in mono.  The speakers do truly disappear and the soundstage is incredible.  I never really thought a pair of speakers could place a singer or an instrument with with such precision.  Sometimes I swear the must be a center speaker between the blades.  It has been a long time since I've stopped trying to replace some component, but for at least now, I'm there.  Perhaps a pair of mc2301s one day, but benefit/cost is getting marginal at this point and the equipment too big.  

I also have a KEF LS50 on my imac with a chord mojo, decware zma amp (40w tube) and a small subwoofer (velodyne minivee 8").  I'm not a fan of subwoofers unless necessary but the little ls50's can only move so much air.   I've tried the wireless LS50's but wound up returning them after a week.  They had much better low end but they just didn't sound magical to me.  This could have been due to tube amplification on my passives, also partly to blame for the weaker low end.  

Anyway, if you love the LS50's, the Blade's are another level.  I find both of them to be amazing.  I had a pair of Reference 1's for about a year and I would describe those as being close to what Blades sound like, but still missing the low end.  If you happen to be in NYC, you can come hear them.
