USB cables conducor - help

With PC as a source, get the least revealing cable. Decent copper USB cable should do just fine. Just pick one.
Invest in a streamer instead…PC is a bull 💩 streamer and you won’t be happy in a long run. 

What a high end cable sounds like is a complex combination of factors far beyond just the composition of conductor. Really inexpensive ones will take on the characteristic of the metal used.

If you are looking for really high quality sound, then I have to recommend getting a dedicated streamer. PCs are not good sources. However, if you are happy with what you want and feel like tweaking… a good quality cable may help… like well shielded. I would look at Cardas. You have to try them.

I have tried about every combination of PC, MAC, iPad and moved to dedicated streamers. 

I use an apple usb c cable from my pc which is a asus rampage v extreme edition 10 with a 6850k and using a Modious dac sounds okay and drives pretty loud 

this will work fine... 

but get this too (and an extra one of the above cable)

PC? Who could possibly care?

I don't.
