Considering you taste in music I would think the Viennas for sure. Great bass and very smooth upper end. Have not heard the ProAc's so cannot comment. Finally I would rule out the Focals. I have heard the Focals, and while a very good speaker for rock and pop, a little too lively and forward to classical and jazz.
As someone else pointed out, you had the chance to actually listen to all three. What did you think?
