I'm looking to buy a new AV receiver soon and the Denon 3805 looks to be the one to go for on features and performance. However I've also been considering the Pioneer VSX-AX5i and the Onkyo TX-NR801E as these offer PC connectivity in the shape of, respectively, USB and Ethernet ports. The Denon misses out in this respect but I was wondering if anyone has any suggestions on how to get a (digital) signal from my laptop to the receiver? I know you can buy external USB soundcards with analogue and digital optical outputs but ideally I'd like to make use of the firewire port on my laptop. I'm just thinking audio at present but being able to send a video signal as well would be a bonus. Also, looking at pictures of the 3805 the Denon Link appears to be a RJ45 socket, as used for Ethernet connections. So the question is, with appropriate software, would it be possible to use a PC to 'mimic' a Denon device and use an Ethernet-Ethernet connection?
