"I have yet to hear even faint praise for the Pearl 3. "
Are you joking? You must not be paying attention then.
There is plenty of praise for the Pearl speakers, including the Pearl 3. In fact I don't think I've ever read anything but a positive, if not positively glowing, report on the Pearl 3 and the earlier Pearl models. Just a quick google brings up these:

I've never heard a bad word said about the Pearl 3 and I suspect you'd have to work much harder to dig any up relative to how easy it is to find plenty of good notices.
