S/PDIF vs RCA

[danhasmail]

Which audio ports on this motherboard ASUS Rampage 3 Extreme are better, the RCA or the S/PDIF ?? I'm thinking the S/PDIF is better but i'm not positive. I have both imput connectors on my Home Theater System so which should i use ???
thanks for any advice you can give me.
Merry Christmas and a Happy New Year

I'd try each out and use the one which sounds best, if there's any difference.

Merry Christmas!

Sorry, it was late-nite when i posted.
They are pin jacks and not RCA jacks.
There are six all together:
1=line in
2=mic in
3=front spkr out
4=rear spkr out
5=center/subwoofer
6=side speaker out
Plus the S/PDIF output

 

[danhasmail]

that is an "optical" S/PDIF output

s/pdif is going to be a digital signal, and the others analog, the digital signal will be cleaner.
