Thanks for the suggestion. I'll be a little more specific.
I'm not looking to buy anything immediately so I don't have an exact price range, but i'm interested in stuff in the range of $200-$1000 for the entire setup. $400 is just about right. I remember my dad dishing out $400 for an Aiwa minisystem that probably sounds worse than my Logitech's, so i'm certainly not going to argue with a $400 system that sounds good.
As for how I listen to the music, I have a Apple laptop and an iPod as my two main sources of music, so really anything is fine. The laptop has optical out if that is of any significance. I currently don't have a whole lot of space for speakers (Those Onkyo's wouldn't fit), but i'm not getting anything right away and i'm willing to rearrange stuff to fit them.
The only thing with those speakers is that i'd like to avoid, if possible, having a CD changer or anything (besides an amp) that come between the speakers and the computer. So I guess i'm looking for a high end equivalent of computer speakers, although they don't have to be an all in one piece thing, a separate amp is fine.
I'm also interested in hearing what, if any, benefit there is to having a headphone amp for headphones such as my Sennheisers. I'm not looking for particular things here, just wondering if there is any reason for an amp and if so, what.
Thanks again-
