Soundcards with wordclock input

I've read that if you use a common wordclock between transport and DAC, then you can reduce (eliminate?) jitter. I've seen only one card that has a wordclock input made by Marian. Are there others or others that are better?

Also, is it better to use 1) a soundcard with a wordclock input or 2) a USB device (e.g., Waveterminal)? It seens that you would need a wordclock input in the Waveterminal to eliminate jitter between the Waveterminal and a DAC.

Bigamp,
i've got the same hopes as you and am trying to run my DCS elgar+ into a MAC/PC. I've found a few high-end PCI cards with a wordclock input and AES/EBU balanced outputs, but i'm still trying to determine the best way to run the elgar in master clock mode and have the PC accept it. Here's a link to where i've found the cards and the people are as helpful as they can be:

trying to find out what the highest possible resolution is from MAC/PC given this setup, i.e 24/192?

a few of the RME professional cards on the link i sent you have a BNC WC input and appear to output 24/192 via AES/EBU, which, i imagine is quite a bit better than a converted USB to AES/EBU and provides the wordclock solution we're looking for? i'm still a bit confused on how to get the quality of source file we need to get the card to put true 24/192 into the card to make this all worth the trouble?
