Focal Scala Utopia vs Wilson Sasha?

I just sold my Dunlavy SC IV's and ordered the Focal Scalas. Meanwhile, I've borrowed a pair of Ktemas, Franco Serblin's new floorstanders. I miss the big sound of the Dunlavy's. I hope the Scalas don't disappoint. I wanted a speaker with modern driver technology, but so far I kind of miss the big SC IV's. Am I crazy?

i take it back. the ktemas have such great resolution and imaging.....

avoid accuphase, go with vitus

Its not boxing to different speakers!!!!HELLO!!!!

I know I'm very late to this party/thread, but have to jump in.  I appreciate everyone's efforts in trying to explain their different experiences and opinions with these two great speakers. It has helped me. 
I just sold my Sashas (had them for ~18 months), and picked up some Scala (v1) here on A'gon.  
If anyone is still interested, I'll share my thoughts when I get the Scalas.
Ancillaries:
Initially, I'll be powering with ARC (ref 3 to ref 75, non SE)
14x21x10(h) dedicated room. Transparent Ultra cables, Lumin T1 source.
I'm interested to see how the Ref 75 does.  It couldn't quite control the Sasha's splashy highs.  I did have a 150SE, which did better across most qualities than the 75, but lost a little charm and warmth. 
Let's see how it does with the Scalas. 
What do you use to for powering your Scalas?
