Good advice from Pabelson. You've got a perfectly fine setup and the important thing for now is just to enjoy it.
After you've listened to it a lot, with all kinds of music at different volume levels, you'll be able to accurately judge what you're hearing from it and, more important, you'll have a reference from which to compare other equipment if you decide to audition something new.
Ultimately you might find a higher powered amp you like better but it's probably just as likely you'd enjoy a lower-powered but higher-quality amp. It's a waste of time to start thinking about that now, however. Listen and enjoy.
