bookshelf or tower

[rayray8]

i am debating on purchasing a set of new paradigm titan bookshelf speakers for my fronts. i currently have a set of polk tsi400's right now. now i only sit 8 feet away from my front soundstage. is it better to go with a bookshelf on a stand vs. towers since i sit so close? am i getting all i can get out of the towers being that close? i just heard the titans and am loving the way paradigm speakers sound! {the signature series were the best i have heard to date}
