Kef Blade or Kef Blade Two for bigger room


Hello all, I am thinking of changing my old bw 800 matrix speakers for the Kef Blade or Blade two.

My living room is 4.8m by 9.3m, with partially sloped high ceeling, and also in the middle going over into my open kitchen adding another 2.5m by 6m... 
Logically I would go for the biggest Blade to get the most and deepest bass response, as most speakers I have tried are too bass shy in my room, except for the big bw800 matrixes, which I set up in middle of the room, and sofa against wall to get bass...
Amplification are Rowland model 9T, so they should get the job done with both speakers.

However I heard from a dealer that the Blade two are better, more coherent sounding, even for bigger rooms; he claimed the big Blade sounds less coherent, with bass floating in the air somewhere and a bit disconnected from the rest...
In my personal experience I heard a Blade two driven by Electrocompaniet Nemos on a music show, im a large rectangular room, and they were brilliant, also in bass.
  i heard the big Blades at a dealer with my model 9t s and they were great as well, but strangely bass shy... room was large enough, but had sloped ceelings to the sides, and the speakers stood on small transporting rollers, so 10 cm higher then normal... Is it possible bass is better from the small blades after all??
Advice would be greatly appreciated! Maybe anyone heard them side by side in same room and with same amps?

To be fair, I did not get to play my own music on the big giyas... so that could put them at a disadvantage to reach me emotionally... Price difference is there though... the smaller and less pricey giyas simply put the soundstage too low for me...
I also have heard the Blade with Hegel gear and then 10 minutes later the Vivid Giya G1 Spirit with Luxman $65K amps. I preferred the Blades. Different strokes. Both rooms were nicely sized.
Hegel with Blade was probably Blade 2...
To get back on topic...🙂 This post wasn’t really Kef Blade vs Vivid Giya but Kef Blade one vs two...😎 Anyone else had a chance to compare both? Thx
The OP has an interesting dilemma.  KEF Blades powered by a rack of Macintosh gear absolutely blew me away at an audio show I attended a few years ago, easily among the very best sound I heard at the show at any price.  If not thunderous bass, it was at least very visceral.  I was awe-struck by the sound of them, really.  If I had the real estate for a pair, I would have them in a heart beat.
