Soundcards with wordclock input

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?

It seems like we're in the same boat, since I'm considering the Elgar+ (or the DAC6e). Currently, I'm leaning toward a device that converts USB to digital (e.g., s/pdif, AES/EBU, or I2S). There's no jitter with USB. I'm pretty sure that USB won't do 24/192, though -- I'll let the Purcell or DAC6e upconvert 44.1. But it seems like the UBS-to-ditgital box could still benefit from a wordclock to eliminate jitter between it and the DAC -- I haven't seen one with a wordclock. Empiral Audio and Hagerman make USB converters.

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?
