Well my Logitech z5500's decided to kick the bucket last night and I am now in need of a new speaker set up. I really don't want anything thats not as good as the z5500s, but I kinda want something new. The biggest thing I need is an optical in connection for use with the optical out on my MBP and my Xbox360. My next biggest requirement would be at least 500 watts, to match that of the z5500s along with a nice subwoofer. My next requirement would be cost. No more than $400 really, since thats what the z5500s retail at. I guess what I'm looking for really is a HTIB (home theater in a box) with optical in connections. If you guys have suggestions of any speaker types, please let me know! I'm open to suggestions. Thanks everyone
