The problem is that the standard came after the devices. Whats the point of a 
standard when no (or only very few devices?) support it?

I still don't get why you want to have 96kHz but only need a stereo-out. For 
quality? Why then go with a small TRS output? And why go with a cheap usb 
soundcard? The output amplifiers and dac will be cheap, which will drastically 
reduce that "gained" quality of 96kHz. Probably it will reduce the quality 
below that of a better-brand 48kHz device...

Have fun,
