USB DAC and/or Musical Servers with USB 3.0 port?

Does anybody know if audio manufacturers moved already or near release of equipment(s) with USB 3.0? Sure, they need different motherboard etc but hi-res files e.g. 24/176 (Reference Recordings) can be played in real time and EASY.

APL HiFi ?
Playback Design ?

If you build your own music server then its not a problem to get right equipment... I only have no idea if JRiver and other similar software can take advantage of the UBS 3.0 hardware?

Thank you
Good point, I'll buy that, Larry.
But Sidssp, 3.0 is 1 higher than 2.0!! :^)
But transferring audio data at 24/176K only requires about 4.2Mbps bandwidth, less than 1/100 of the USB 2.0 spec. What difference will it make to go up to 5Gbps?
The theoretical throughput improvement offered by USB 3.0 is dramatic -- a theoretical 10X jump over existing USB 2.0 hardware. USB 2.0 maxed out at a theoretical 480Mbps, while USB 3.0 can theoretically handle up to 5Gbps. Mind you, applications like storage will still be limited by the type of drive inside. no I don't know a manufacturer
What advantage does USB 3.0 have over USB 2.0?
