Mel, pass the popcorn.
HTGeek, if that's the itch you want to scratch, I sincerely hope you have a great time. My opinion is that unless you are listening at fairly high volumes and are dissatisfied with the results, you're not going to get good "value" for that upgrade.
Krell makes great (and disproportionately expensive) amps. Getting a good used amp from Audiogon can be a good strategy; with no moving parts and no processing to speak of, amps are a pretty safe used purchase.
Lots of people have had success with pro style amps (Crown, QSC, etc.).
