I don't understand your need to post a picture of "yourself". Was this an attempt to get guys to think you might be a female and get all excited? If so you blew it, you've got to show tits or ass to get us excited. . . and most of us here could care less what sex you are when it comes to music questions.
Anyway, back to your question(s).
I recently bought my daughter one of thesehttp://www.bestbuy.com/site/olspage....=1077625490200
It had the combination of features she wanted - aux input for her ipod, Cd changer (though she doesn't use that much anymore since most of her music is on the ipod).
It was by far the best sounding unit I could find for anywhere near the price I wanted to pay.
It has alot of useless gimmicks, but, underlying them is a fair quality unit for the price paid.
I did not listen to the JVC unit you linked to. I've read they are pretty good, but, that was more than I wanted to spend for a cheap bedroom system. If I were to spend more than a few hundred bucks on a bedroom system I seriously consider getting a component based system. But that would take up more space. . .
You really need to figure out what is most important to you.
What is your budget?
Does the system have to be compact?
Do you want bass thump, or, are you willing to give that up for better midrange?
Any special features you want?
You want a CD changer - shouldn't be a problem (although the Phillips player I linked to above might not be the best choice for that because the changing mechanism is noisier than it could be).
You mention DVD - do you also want video output, and more than two speaker sound?
In the end you have to go listen to a bunch of stuff and pick what you like, and look for features you think are important. Then balance that with your budget. You look like a smart young lady, you should be able to do this. At most every price point there is stuff that sounds good to some people, but not others. At the lower end you are looking at there are bigger comprimises than some of us might like. e.g. if you value appearance more than sound you might pick a different unit than I did for my daughter.
BTW computer stored music can sound just as good as CD music. And once you get it on your computer it is much more convenient.
Hope this helps, and feel free to post more pictures ;)
