i have just finished building a windows media center pc, which i want to connect up to my philips 42" plasma screen

i am connecting the media center to the plasma screen through a dvi cable so there is no problem with the video,

however now i am left wondering how i can get the best sound

i am looking fror some surround sound set of speakers, and i think a a/v reciever ? (is this setup correct) i am open to all and any suggestiions. i am very new to this.

i want the system to sound amazing and i am not affraid to spend a little money to get it.

thanks for your help
