I am very happy with ES9018. It is a 32bit/192kHz DAC. In practice it can work with sampling rates up to 384 kHz. USB is not limited to 48 kHz. There are many devices on the market that can handle much higher sampling rates over USB.
Correct me if I'm wrong, but all the usb audio ICs that can handle 24/96 or more (let alone adaptive or async mode) need some kind of firmware configuration and do not work out of the box like the pcm270x and the likes.
So if you got the required programming/hardware skills or if you are eager to learn (this is not going to be easy or fast), you can possibly make your own USB 24/96+ receiver.
The easy way is to incorporate a module that is capable of 24/96+ (you need drivers and the right IC for sampling rates more than 96K or 24bit from USB if you are using XP, I'm not sure about 7 or linux) or a product like m2tech usb to spdi/f converter.
One thing I forgot, TI used to produce the TAS1020 and provides a firmware development kit (software) but now this is obsolete/not recomended for new designs and has been replaced with a DSP (BGA package, the one with all the pins lying underneath to make even soldering impossible ), so now it is out of the question for a regular DIYer to work his way out with this...
What do you guys think about these:

Especially the second one
.Tenor won't sell small quantity of the TE7022.
Guess what
I'll get 2 of the ESS Sabre 32 chips at 50$ each,so...
the 32/384 USB controller then?Wrote to VIA,still no reply.Any place I can buy the thing?
It's a university project.Money not objective to some extent.Wow,it's gonna be the high-end monster
