Joseph Audio: Perspectives and Pearls

There have been several recent threads that have included both of these speaker. However, much of the discussion has focused on the Perspectives, with a number of positive reviews. I am quite interested in hearing them, but am also seriously considering the far more expensive Pearls as well. 

I am wondering if anyone has done a direct comparison or has upgraded from the Perspectives to the Pearls?  I am specifically interested if the Pearls might overwhelm my room (13 X 18 with 9 foot ceilings) which is not a space dedicated to my system (it's my living room.)

Thanks in advance for your experiences with these two speakers.
