That's a hard one to answer.
I am not so worried bout the price as much as the quality sound.
Both are good speakers, come from reputable companies and are well built, but "quality sound" is a tough bird to define. PSB is more of an "upscale" brand but that doesn't guarantee you will like their sound any better than what you already have.
Both produce "quality sound" as defined by their designer's intent and their fanboys but, for us, "quality sound" is in the ears of the beholder. It's a personal decision you have to make. We really can't offer any valid advice there. We might be able to state our preferences but that may or may not reflect yours.
If it's any help, I prefer brunettes but your tastes may differ.
I do suggest, however, that when auditioning these you take along some music you're familiar with and leave the movies out of the decision making process. Virtually all speakers that sound good on music do at least as well on movies. It doesn't seem to work the other way around, though.
