Onkyo's lineup of network enabled Home Theater Receivers are absolutely incredible. They allow you to stream music, pictures and video from your Windows based PC or any DNLA compatible device (e.g. Sony PS3).
On top of that they also allow you to stream content from your Rhapsody, Napster, or MediaFly account.
That's just the "gadget" part of the receiver. Where this technology really shines in absolutely stunning clarity of both Home Theater applications (Satellite, Cable Box and Blu-Ray movies) and pure audio sources (MP3s and CDs). If you are looking for a killer setup with a great bang for the buck look no further than Onkyo. I'm a proud owner of a Onkyo TX-NR3008 and I absolutely love this system
