Any audiophile would know that you don't use the transmitters because it does not enhance your listening experience. That the normal Joe might not doesn't change that I wouldn't recommend it because I wouldn't like it.I have a plasma screen HD TV. You exaggerate the difference in your mind - placebo effect. It doesn't improve the "actual" viewing experience much. I know what I'm talking about, you don't. Case closed.
And it may not enhance your "viewing experience" much, but it certainly enhances others experience, and it isn't all in their head. They like the crisp picture, and you are nuts if you don't understand how it enhances movies especially as they don't need to cut them up so badly in order to get them on your TV.
