Coaxial cables and s/pdif cables?

When you say s/pdif do you men optical? If so it an be interconverted to digital coaxial (orange RCA jack) using a converter available for under $20 from any number of places (see link for one option). Note there are optical to coax and coax to optical converters .. you need to get the right one!. You will also need an optical cable and a coax cable (although in the latter case you can use a regular RCA audio cable).
