heres the bottom end of high end audio. I have a simular setup, note! the KLH speaekers don't scream clarity, or quality, however, for the price they kill evyerhting else! they hit lows better than a lot of subs and the do a pretty nice job on highs, they arn't shilded so give you tv a little space from the woofers but they will rock youwrold compared to a crappy all in a box system. the reciver, honestly an ugly piece of crap, I would recomeneding springing forwad and buying this

then you can move to surorund later, and you can add a dvd-a player.
and that is of course a nice DVD player if you have a component input tv, if not I would move towards you $30 dollar player or buy a ps2
thats pretty close to your under $300 request and defintly under the $400 logitechs. to get surround I would just buy andother set of KLH toweres, for DVD-A, but you get get a really nice system for $450.
