USB to I2S that supports DSD

I've looked and looked and can't find an outboard box that converts USB to I2S and supports DSD, or an PC internal sound card that outputs I2S and supports DSD. Maybe I'm just blind, dumb, and deaf.

I just came close to purchasing the Pink Faun I2S bridge, but then realized it doesn't support DSD out, which would mean JRiver needs to step the stream down - rather not do that. PFaun also has a FAQ that dis's the whole dsd format, and then says later versions might support it.

My digital setup is a good quiet PC with USB out to the Wyred DAC2 DSDse. (Yes, I know a dedicated server would be better). I figure it's now time to take advantage of the I2S input to the Dac. But, there doesn't seem to be any solution for this in either an outboard converter (which should be superior by avoiding PC noise) or an internal sound card.

I see the Amanero Technologies card, but it would require me to build a box for it - seems like someone ought to have done this by now. There's the Off-Ramp 5, but like the PFaun, it's limited to 24/192.

Any help out there?

The Gustard U12 looks like it does this. It is cheap and has received positive comments on the head-fi forum. I can't vouch for it but I am curious if the I2S output is good. For $150 to $200, it may be worth a try.

In speaking with W4S today, they remain enamored with the USB especially with the Femto clock - which should be back in my system end of next week. Their advice was to not go the outboard usb to i2s converter route just to avoid more processing and boxes and connections along the signal path. And, at the moment there still is not a good i2s pc card out there that can handle the dsd bit depth. Further, W4S did not seem to think that i2s into the w4s would be significantly better than the usb, if at all, which seems a bit surprising.

At this point, I think I'll switch gears and consider simply improving the USB output from the pc itself. Right now, it's simply usb off the motherboard. Perhaps the SOtM card with their fan and power supply tweaks. Has anyone tried these?
