Why would you want to use USB for audio? You can have an inherently noisy signal, apparently.
By the way, I don’t class myself as an audiophile, but I have a reasonable system on which I enjoy my music.
If streaming I use my Z97 Asus Maximus Hero, an i7-6700k with Zalman FX70 cooler. 16Gb ram (because it was a little bit more expensive than 8Gb). I have a passively cooled GTX760, and an Asus Essence STX II sound card. OS is on one SSD, and music on another. It is all fitted in an R5 case. I connect it to my system either using a coax cable from the STX card to my DAC, ot a coup,e of home made RCA cables.
Is it the best thing since sliced bread? Of course not, but for a PC built mostly using parts that were lying around, it sounds pretty good to my ears, and to be honest, that is all that counts.
I personally don’t like buying audio cables, as you pay a lot for the marketing and dealer margin etc. Everybody in the chain makes a bit, so you pay a lot for pretty basic cable. Learn to solder, and you can make some pretty good cables for not a lot of cash outlay.
