If you bought your TV at anyplace that was worth a damn, they should have explained to you what you needed/should have to go along with it. As a former Entertainment Department Sales Manager for Circuit City, I can honestly tell you that the quality of the TV you bought will dictate whether or not you should buy better cables, etc. What brand is your TV? A good plasma like a Sony, Pioneer or Panasonic will benefit from the better cables, whereas with an Akai or Symphonic or some crap like that you'd basically be wasting your money on better cables. Hope that helps. PM me if you want more specific advice.
