Golden Ear's Triton Two is a tower with a powered sub in each tower. I've heard them, and they sound pretty good. They weren't as crystal clear as I would have liked, but I heard them immediately after listening to Magnepan 3.7's. They would definitely improve the base on your stereo listening. Vandersteen 3A or 5A's would be a good speaker. I would definitely recommend Maineiac's suggestion.
Personally, if I were putting together a system for classic rock, I'd get some of Zu Audio's Soul Superfly's and run them through a Dynaco ST-70 and a Conrad Johnson PV5 and just keep the 803's for the surround setup.
