96 KHz, you mean.. The Wolfson DAC can go higher than that but I'm pretty sure the Chaintech cards aren't capable of outputting those rates to the DAC. It depends on the clock crystal used on the card (you need a 49.152MHz clock for that, I think, and the Chaintech uses a 24.576MHz).
As an aside, the S/PDIF output from the card and the output to the Wolfson DAC are the same output from the Envy24HT chip. This is how you can use the Wolfson DAC when not in high-sample rate mode, just by switching on digital output - the Wolfson DAC gets the signal as well. This is also why digital output can't be turned on in 7.1 channel mode (the Wolfson DAC is used for the extra rear channels in this mode, and digital out would only give you those channels on the digital output).
