I would like to upgrade mt HT but don't have the foggiest idea where to start. Currently have a JVC theatre in a box system. TV is wide screen Mitsu #wt46807. Please help with some suggestions. Budget is approx. $1200 for tuner and $1500 for speakers and sub. This is my first post if I have not given enough info please let me know. I am willing to take the time needed to make this decision the right one.
