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
What advantage does USB 3.0 have over USB 2.0?
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
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?
But Sidssp, 3.0 is 1 higher than 2.0!! :^)
Good point, I'll buy that, Larry.
