I currently have a cs300 with RT800 fronts. I've been very happy with my setup for years and still really like the RT800s. However we have moved into a larger home where the viewing/listening distance is about 17 feet (don't worry...tv is huge). So I'm wondering if it would help to upgrade the center for better performance at that distance. If I do upgrade I'd like the difference to be very noticeable or I'm incline to stay with what I have. Suggestions?
