If I had to take a wild guess, this "desktop changer" coming in a few weeks is either:
a) A new digital audio computer interface using eithernet
b) A direct streaming device where it has wifi/ethernet built in, yet is controlled by your computer via USB.
The issue has always been either clean up USB audio or go around it. My guess is a go around solution, same as you are doing with other devices.
It is just too bad that USB 3 and/or USB-C is pretty much just as bad with higher power rails. And also too bad Firewire/IEEE-1394 did not take off more. Apple abandoned it once they could no longer make money on licencing anymore and the market was pretty happy with USB 2.
All that said, I do agree that any DAC can have an improvement by using external powered devices to convert the USB into S/PDIF. For one, you are not supplying power or signal to that USB receiver chip, but also a dedicated device usually does it more efficiently because it does not have to worry about power consumption or other things.
I use a Wyrd hooked into a Peachtree X1 that then outputs S/PDIF. I has an XMOS chip just like my X3 II, but the X1 sounds better. Besides, the X3 II is limited to 24 bit output - fine for most I suppose.
Why not Firewire's successor—thunderbolt?
