Folks, I will be building an audiophile/home theater system soon. I'm starting with 2-channel and want to make my way up to 4 (i don't like center channels). I'm using my computer as the front end. I'd like to use USB, Firewire or wireless as my "transmission lines". As far as multichannel goes, i'd imagine that even if i split audio into front and back and sent each to a wireless Slim Devices Transporter ( http://www.slimdevices.com/pi_transporter.html) that the two tranporters would not be in synch. So, is a firewire device like the Apogee Rosetta 800 a solution? Will a linux movie player using xine or gstreamer be able to send the correct channels of the Dolby Digital/DTS to the individual channels on a multi-channel pro device? This all assumes that Freebob (the firewire driver) works as advertised. I realize i can just send a dolby digital/DTS signal to the Transporter and then on to a pre/pro but that adds another link in the chain. Thanks all.
