No, that's pretty good! Shredder - the Ethernet interface on the SB, the Transporter and any NAS is for computer communication only, not audio. It can be used to send Internet data or computer files. The SB and Transporter use it just like the wireless interface to receive the raw computer files. They then decode them into audio. What's potentially confusing you is you can use Ethernet patch cable to send an audio signal, but really you're just using the wires as you can use any wire. You're not using them as computer communication conduits at all. You can use the SB/Transporter this way, there's gear you can get to send the analog audio down Ethernet cable and get it back to analog audio on the other end. But note that we're not using the SB/Transporter/NAS Ethernet port for this, we're merely using the copper wire that comes in the Ethernet cable as we would any wire. For a NAS to be used this way, it would need a sound card and they almost always don't have one. You'd need a PC with a proper sound card. It is possible with SlimServer and Softsqueeze but it's not as elegant and simple. With a good soundcard and a Benchmark DAC the sound could be better than an SB alone but it will have a hard time beating the Transporter as the Transporter's DAC and power supplies are very good. Using the Transporter's digital out is a waste of its DAC, you'd really be better off with an SB + DAC or a PC + DAC. I don't see what advantages the PC + DAC would give you over the SB + DAC, for one thing it would be more expensive and could never be as quiet because there would have to be at least a hard drive in the PC. I've been accused of being a fanboy and I don't want to dissuade you from the PC (with soundcard) + DAC route, but in summary, a PC + DAC may be better than an SB alone, it may not be better than an SB + DAC and it will probably not be better than a Transporter using its built-in DAC. -- Mark Lanctot ------------------------------------------------------------------------ Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=40647 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
