Can someone answer a question about SPDIF?

I'm getting ready to get a new sound card and a set of Logitech Z-5500 speakers, but the sound card doesn't seem to have the same SPDIF connections as the decoder.

This leads to my questions. Does a coax digital signal sound as good as a optical digital signal? Also, the sound card says it has an analog SPDIF output, but the input on the back of the decoder doesn't have the same kind of jack that the output on the sound card has. So, looking at the picture of the back of the decoder, does the SPDIF output on the sound card resemble a normal headphone jack and does the coax SPDIF input on the decoder resemble an RCA jack? If so that means it will need a special cable, can I expect this cable to show up in the sound card box?

I don't want to order the sound card and speakers to find out they're incompatible so I'm doing my research. Do you have anything else to add to this?

Thanks
 
Use a 3.5MM to RCA adapter, and run a regular RCA cable from the Audigy's Digital Out to the Digital Coax on the decoder. I use something like this, just use only one rca plug.

Last I read, typical coax cables had greater bandwidth than consumer optical, so the reverse would be true, assuming that the resultant jitter / any other artifacts are audible, which probably aren't, at least in the vast majority of cases.

OTOH, optical isn't going to be as succeptible to noise / EMI for similar effects on jitter / etc..

Overall of course, none of this is going to matter one whit compared to everthing else in the audio chain.
