With the 4802 going a little more than double the price of the 3802 is it really worth it? What does the price of the 4802 get you? I am in no need of the 4802 THX processing (just the THX like crossover frequency and slope). For the money it seems like it would be better to go with the 3802 and external amplification. Anyone have the 4802 and think it is worth it over the 3802?
