Call me old fashioned, but it seems like wireless speakers wouldn't be able to match the quality of wired.

I think I might just try and find a banging klipsch system.

Here I come again to throw the spanner into the works.

Your card says it's Dolby Digital certified because it actually has a Dolby Digital EX/DTS ES decoder on board. (At least the older X-Fi range does, like the Audigys before them)
I shall explain.
To make use of this, when watching a DVD, select S/PDIF audio output in the DVD software's option menu and the raw audio will be decoded by the soundcard in hardware, rather than software. At least that's how it used to work under XP anyway. That feature doesn't work properly anymore under Vista. Quite a useful feature I must say. To be honest, the sound difference between the two is so small it's not worth fussing over.
Where the hardware decoder comes in under Vista is another perk unique to the Creative line.

On my old X-Fi Platinum (it was basically an Xtreme Music with a handy front I/O bay) I was able to connect my 360 to the PC via optical and have the PC decode the the ac3 or dts stream for me. I didn't have a reciever at the time and just a cheap 5.1 set up. This meant the card would decode the audio and output it to the correct channel, a bit like an expensive reciever. I don't know of any other cards (other than the Audigy 2) that could do this and it was a brilliant idea on Creative's part.
That is what it meant when you saw the Dolby and DTS logos all over the box and the marketing pages.

Sadly according to Creative's site, the newer cards do not retain this feature and everything needs to be done in software now. This is why, even though I got a Xonar D2x yesterday, I am hanging onto my Creative card. The software and the company suck balls, but the hardware is excellent.

Anyway XaNe is right about outputting audio via digital. Get a simple 3.5mm to RCA (red/white plug) cable and do it that way. One of the cables will have audio on it.

With regards to outputting 5.1 audio via digital on the otherhand, around 6 months ago you would have been correct.
On release cards only did 2 channel PCM. They could pass on an undecoded DTS/DD stream, but couldn't actually process it. This is where the onboard decoder came into play, as Creative assumed everybody connected their speakers via analogue. While for a majority of people this is still true, more and more people are taking the digital route.
In short, all X-Fi cards (except the Extreme Audio - it doesn't have an EMU20K1 processor) can now have an upgrade, allowing them to output audio in Dolby Digital Live, or DTS.

I've tried the upgrade. It works fine. It's not as well implemented as cards containing the C-Media chipsets. It is encoded in software, (ASIO to be exact) not hardware meaning when it's enabled it will use around 4% of your CPU at all times. But on the otherhand it does mean you can have "true 5.1" via your digital out.
If you have an older Creative X-Fi card, (especially the Platinum or Fata1ty cards) seriously hang onto them as when combined with the cheap DTS/DD upgrade, their feature set is unbeatable.

Think that's everything...
