You can not tell me watching Black Hawk Down (won the award for best sound that year) is the same sound on the TV as the 5.1?  Feeling explosions just does something more than hearing them.  One thing I know I will miss is high fi audio equipment for both cars and the home.
One thing you may gain is live drums from close proximity - I've had the chance to hear and play (with) some large taiko drums - talk about feeling the music!

 No, I can't. Nor Lord of the Rings. Nor any outer space show.

  I won't miss high fi, cuz I have solar, and I have concert DVDs. (And lots of other, less high tech, forms of stored music. Even something from the last century called  "records".)
