imo if ur looking to get an all in one system for 300, then you would be better off keeping the system (as crappy as it maybe) for a while and spend a lil more.
if i could suggest, that is if you can afford it,
jvc receiver and then possibly a set of
jbl speakers
my setup here at my house: kenwood receiver, 2 floor standing jbl speakers, center channel and 2 infinity surround sound speakers. i slowly built my system i used to have just the kenwood and 2 jbl bookshelf speakers in the front(50 each, late 90's). also i have all monster cableing, I have had this setup for a few years, total i prolly spent about 700 without tax and shipping(for some of the items). I am not trying to brag just saying that with the above system, with say saving private ryan in, it sound like you are in a movie theater!
this is my suggestion to you if you would like to have a decent system without costing alot of money.
