That depends on your speakers.
Select your speakers first. Then worry about buying a receiver to power them.
...and always buy the biggest, baddest subwoofer you can afford. You can always turn a powerful one down but you can turn a weak one up only so much.
One other tip... Since you say music has a place in your future, I suggest that when selecting your speakers, use music, not a movie. Too many times we hear that speakers sound great on a movie but lack on music. I can't ever recall hearing someone say they sound great on music but not on movies.
oh, one last thing... I know you're new here and didn't know, but It's considered bad manners to post the same query in multiple forums.
