I'm glad you enjoy them!
If I went with the JBL's I would likely go for the 580's as I don't think I would be happy with the 570's. As such, the overall cost was a touch more than I wanted to spend. I ended up purchasing the CMT-340 SE's, 170's for side surrounds, 340 center, and a FV15HP.
Perhaps when Summer rolls around I will pick up a set of the 530's for music listening along with a nice amp to push them.
Thanks for everyone's help!
