Coaxial Digital VS Optical Digital
Ok .. I plan on getting a nano-itx board to use for my car pc. All these years I've been planning to have a fibre-optic connection between the car pc and the amplifier so as to get the best audio signal possible without losing much quality. I know this is probably going a bit far, but I was hoping for VIA to include an optical digital output on the board, but instead they've included a coaxial digital output.
I understand you can buy a converter that converts coaxial digital to optical digital, and you can get one to do the reverse.
My questions: is it really worth having an optical connection between the source and the amp? And will it be better (a whole lot better?) for surround sound, given that I intend to buy a 5.1ch car amplifier that has an optical input (I had the links to some of these ... but I can't find them now ..)
I also understand that optical cables are less susceptible to electrical interference from other cables/devices, and car pc installations are notorious for interference problems if cables are not run correctly.
Your thoughts would be greatly appreciated.
Note: my current motherboard in my desktop, an MSI Neo4-Platinum has coaxial digital output AND optical digital output on the back panel .... very very nifty! For my car pc, I would ideally like to use a nano-itx. If there are any mini-itx mobos that have optical output, please let me know.
