I don't know these models but I have "compared" the Wilson Audio Watt/Puppy 7 with the Sonus Faber Stradivari. Well compared is a big word. There is a shop in Leiden who sells both and I had a quick listen to both. I think Sonus Faber makes great speakers, they are never fatiguing and et you hear great many details. But they are rather dull, maybe to polite could be great if you listen to Jazz and some classical (chamber music). If however you would like some more guts, less polite, maybe fewer details but more oomph, the Wilson Audio's were better.
I preferred the Wilson Audio.
