I think home theatre is very enjoyable and not that hard. While my 2 channel system is what I consider high end, my home theatre is relatively standard wtih a Denon 4700 HT reciever. I use pre out from the Denon into my 2 channel amp for the front speaker and then have relatively inexpensive speakers ($1000 a pair or less) for rears and surrounds. 2 relatively inexpensive subwoofers and Top Gun sounds like I'm on deck.
Good luck,
Jerry
