Can anyone give me a better understanding of THX, I realize that the equipment has to undergo certain tests and pay a licence fee to get this, but do they sound any different on movies that have THX certification?
When the upgrade bug hits on a new receiver, I would like to get the Audyssey auto setup, but am wondering, as posted in another thread if the THX is worth the extra expense.
