The present invention is to provide a network audio file receiver system for connecting a home stereo to a wide band network, which comprises a network audio file receiver coupled to a home stereo for receiving and playing audio files sent from an Internet radio via an Internet protocol sharing device and a wide band modem when the wide band modem is coupled to the Internet. When the network audio file receiver is not coupled to the Internet, the home stereo is still adapted to play audio files downloaded from the Internet and stored in the hard disk of the PC.
