@givin2u - are they worth it? - well that depends on your component that is being connected.
If the component uses the USB power provided by the cable - then yes - they are worth it!
Take a look at

I think Pangea also makes a dual cable
Separating the signal and power eliminates noise being induced across the conductors, which ultimately contaminates the USB interface circuitry with noise.
The Doukmall/Pangea cables above will prevent this. Sound quality will be improved
If the component has a separate power supply then a dual cable may not be required
But it is not quite that simple - My Bifrost had it’s own power supply - however, the USB interface card actually used the USB power. The later versions have rectified that design to use the on-board power supply.
Also, some devices like the Musical Fidelity V-link192 successfully deals with the power issue internally - so you really have to delve into the deign of the component - or simply spend the money and see if sound quality improves - or call the company and ask them
Hope that helps - Steve
