Why not just use Coaxial when it comes to computer audio?

im new to the server/computer side of lossy audio. Im researching, buying and learning as I go with regards to amps/dacs etc

but it appears that not only is USB problematic with regards to sampling rates, clock issues, jitter etc, and most of the USB/spdif/coaxial converters are very expensive for the actual components involved (not disavowing the costs of actual intellectual property)

but with most onboard motherboards having coaxial outputs, even sounds cards as cheap as so the D2X also having coaxial

why isnt the standard interface just coaxial for computer side audio?

I know laptops are always a consideration, but if the consumer demanded this, it seems more manufacturer's would head this way

is there any inherent plus to using USB or something that im missing?


thanks for the help

I could be wrong, but I don't think a coaxial connection can supply power, but USB can. So for semi-portable DACs without their own wall wart, USB is the way to go. Most DACs that have their own plug do have the option of coaxial.

that is true, on the power issue

but most of my portables have rechargeable batteries, but I guess that makes sense why it would be easier to use usb power


just seems like the inherent design of usb, originally as a peripheral access, is far more troublesome, and the coaxial output would just be a cleaner line of connectivity

Portables have to be charged somehow. And no, most semi-portables don't have batteries, that's why I said semi-portable. They aren't for use with iPods, for example, but for laptops or are transportable. The NuForce uDAC, Behringer UCA202, X-Fi Go!, ASUS U3, Fiio E10 are examples.

 

I doubt you'd hear a difference between USB and coaxial if they're both utilized properly.
