Paradigm vs Dali vs PMC

Hi I posted a thread earlier. I have narrowed down my choices to the following and wondered if anyone had any tips or experience with either. Its for a room about 17 x 17, with a Simaudio 100W I-3 amp (considered tonally neutral)....the list is

(1) PMC FB1i (a recent update on FB1+), new soft dome tweeter
(2) Paradigm S4 V2 (anyone know if the Beryllium tweeter is hard/harsh)?
(3) Dali Mentor 6 with the ribbon tweeter

I have listened to the Mentor but a bit concerned the lower midrange/upper bass is a bit lean sounding. I only heard the Paradigm through a Yamaha AV amp which may be tuned to be bright? Going to audition the PMC on Monday.

Thanks for your help
