Sonus Faber speakers - what's your experience?

I didn’t find them difficult to place at all, but be aware that their sound signature can vary pretty significantly between their lines so keep that in mind. 

I also liked the sound of the Sonus Fabers at the Audio Advice event.  I believe on Friday they were the Lilium, so 1 step down from the Aida but still $75k.  To me that was the best sounding room at the show. 

How finnicky are they in placement compared to, say Wilsons?

They’re wonderful speakers that do many things right and look gorgeous as well. If you’re looking for neutral or detail monsters, they might not be for you as they tend to be a little on the romantic side of things. I owned Olympica II and really liked them. Wouldn’t mind owning another SF in the future. I didn’t find them to be fussy with placement but they do give you more if you provide more breathing room. 
 

I only sold them because I wanted to try something different and not necessarily due to any shortcomings. Having said that, I preferred the Olympica line over Lumina. Not a huge difference but Olympica had a bit more of the SF magic. Of course they continue to get better as your move up in the lineup. 

Thanks, @tosnc--I wasn't completely sure on what I thought were the Aida's.

And, thank you, @arafiq & ​​@soix, for your input; all good to know!

When tweeter carried SF I only remember trying to sell a kidney to get a pair. I still think of my VA beethovens as poor mans sonus faber
