If this rumor is true, it is likely that the issue of 24/96 is tied to updates in iOS versions for Apple devices. It would not surprise me if the capability would be limited to Lightning devices alone.
I can get 24/96 out of an iPad or a newer iPhone, but only with either of the two CCKs, not the stock cable. I have not heard of anyone who can get 24/96 out of an iDevice using a stock 30-pin or Lightning cable. If it were possible with any DAC, I think someone would have reported it already.
On the good news side, this means there should be more people offering short Lightning-to-USB cables soon. I have two short 30-pin-to-USB cables to use with my M8, but no short Lightning-to-USB ones. Either that, or I need to pony up to get the one from V-MODA; it looks like they sell it for $25+5 shipping.
EDIT: I already have the short one from Amazon; unfortunately they messed up the Lightning end and made it too big to fit through my iPhone case. Slimmer cables, please!
