They were my first setup after using a HTiB. I have the Synergy line in my bedroom. Most will complain about them being extremely bright.
When I first used them, I hated them for music, and they were great for home theater use.
I'm in a different place now, I am using an Onkyo 805 with the F2's, C2, and quintets for surrounds. My bedroom is somewhat acoustically treated (it's kinda a joke, but it is).
I now listen to music with my Klipsch setup, and it's the acoustic treatment that made the difference.
