I've got the F52's and they are an astounding speaker and a fabulous value.  One of the great but unheralded speaker values in high end.  My upstream is all McIntosh.  MCD500, C2200, MC402. 
I'm wondering if the flagship lineup Studio 2 or the Salon 2 must be even better if they were designed to be so.  Can anyone who has heard all three comment?  I'd happily upgrade if this sound get's evn better.  I do not have the ability to audition the three.
