I agree that davening in a shul with a real chazzan at the amud is not davening. Actually when my chevra wanted to go hear chazzan hershtik in the great synagouge in yerushalayim, we would first daven at six, then go to the great synagouge.
that being said, chazzanus in general is a facinating art. i was raised with chazzanus playing in my house almost constantly.
