+1 with Peng.
Not only does having the USB port on the 1912 solve your issue, but I think you would be seriously disappointed later on that you lacked the network capability. Maybe you're not big into Pandora, Rhapsody, Napster, etc. but someday something you do want to use may come by and you won't be able to take advantage of it. Also, Airplay and the Denon remote control app is really nice.
