Hi all. I've just ordered a 3910 but it's occurred to me that I'm not too sure what the best way is to connect it to my AVCA1-SR for DVD-A, SACD & DVD video-audio playback. I've got a HDMI cable ready for connecting to my plasma but wondered what the ideal way is to get all audio from the player to the amp. Currently I'm using optical on my old dvd player but plan to use the DVDA, SACD also on the 3910. I know that DenonLink does not support SACD - should I use firewire? ....bit confused to be honest..
