If it makes no difference in the price of the unit, add them and let the user decide if he or she uses them. I personally never use them, but you never know when it might find material it sounds cool on. The best luck I've had with them is on video games. I always listen to music and watch movies in the direct or standard mode. I want to here the program exactly as it was recorded. I've never needed THX re-eq or any other type of soundtrack enhancement to enjoy my movies, I like them better without.
My vote though........Add them, because you never know. And "Bells & Whistles" are cool!
