I own the Joseph's (Mk2 version) and am extremely happy with them. In my auditioning they beat out comparably priced Thiels (2.4), Audio Physic (Tempo), Revel (F30) and Totems (Forest) but I have not heard the SF's. Thus, I can't offer any comparison.
One thing to consider, however, is that the Joseph's aren't magnetically shielded (I don't think.) Not sure about the SF's.
Good luck.
