Am I the only one to opt-out on the Sopra 2's?

You said it, Paraneer.   This type of thing happens, Hinde, you're definitely not alone.  When I bought my Wilson Benesch Arcs pre-owned, they sounded absolutely awful in the living room of the guy selling them.  If you didn't know what they were, you wouldn't have paid $200 for them.  For whatever reason...room, location, positioning, equipment, whatever, that system was a FAIL.  I bought them anyway because I'd heard them previously at a dealer and I knew they should sound better.  And they do - I listened to the Beach Boys 1964 Sessions album last night, and it was like I was in the studio with them. Just wonderful in my space.  Point being, there are just too many variables in play - a pair of speakers that sound glorious in one room and system can sound completely disappointing in another.   It's not an indictment of your ears, your room, or the speakers...it just happens that way sometimes.

in my limited exposure to Wilson speakers I much prefer them with tube gear over ss

my two cents

fwiw

I've heard very expensive speakers totally fall apart in a bad room. 
Everything in audio seems to be co-dependent. 

I auditioned the Sopras at Apex in Denver.  I was very disappointed in their sound. I found them very bright and not enjoyable with a broad range of music.  Initially they were played with SS Aestethix gear.  I complained about the brightness and Carl switched them over to VAC.  It helped quite a bit, but I still didn't like the sound.  It literally hurt my ears at volume on the high notes.

These speakers, Focal/JM Labs, can be bright if not gear-matched properly.  I have auditioned several older models of each brand. I have not had an opportunity to demo the Sopra models.
