Bedroom system for my 10 year old son


We're re-doing our 10 yr old son's bedroom. He's really into music, listens either to his iPod or the family computer in the den. My wife says we should add a stereo for him. I've got a pair of NHT Super Zero's sitting unused that I can throw in there. What I need is either an integrated amp or receiver. I prefer something in the sub $200 range, preferably with a headphone jack. Because he doesn't have much shelf space, the smaller the footprint the better.

Any recommendation for something that would work with the NHT's? Would I be better off spending a couple hundreds of bucks on a shelf system?

Thanks in advance.

Wow! Thanks for all the ideas.

I had thought about a sub, but the issue is space. The room is about 12 x 12, he's got a bed, a small bookcase, a desk/chair and a floor lamp. Plus one whole wall is taken up with the door and closets. I can mount the NHT's on the wall, so they're not an issue.

Keep the ideas coming.
Pick up a used Great American Sound (GAS) Thalia or Thoebe preamp and mate it to a GAS Son of Ampzilla power amp. Cheap enough on Ebay, fun names, and gets him into having pride of ownership and separates like the big boys. Surprisingly, this gear still cuts muster with today's gear. The meters on the amp are a hoot also.
"12 X 12", you might want to stick with headphones, or at the very least limited bass (not typically the kind of sound kids go for).
Any system would be great, just as long as it has no speakers. The other memebers of your family will never get any 'peace & quite' once the speakers, including a sub, show up. Headphone listening, from the ipod, computer or receiver is best. Spend the money on a good pair of headphones, all will be happy. You will get to enjoy your system more.
Buconero117, your post brought back many fond memories of listening to my music via Koss headphones when I was a young lad. I know Mom and Dad appreciated them !! Ecruz, if you go with headphones, explain to the little man about excessive volume and hearing loss.
