Ok I have a "rabbit hole" question. Porge you can yell at me for asking this here if you like?

I am in this hobby which auto makes me crazy. I recently finished putting my latest HT together and buying everything and its basically done. Since then I have become obsessed with PSA speakers. I have for those of you that don't know Def Tech SM 65 mains, SM 65 center speaker, SM 55 surrounds, SVS PB-1000 sub. I have been thinking of because yes I am crazy with going with 5 PSA MT-110 speakers all the way around. Now I really can't do this now, but wanted to get your take on just how much or if it would be an upgrade in sound quality? I mean would it be a very, very big significant step up in sound quality? The thing is the system I have now sounds really, really awesome. Its really incredible, and I love it. Just wanted to see what you guys think?
