USB cables conducor - help

For your guidance, Nordost uses Silver plated conductors in their Heimdall and above USB cables.

Recommend getting a dedicate streamer first, Bluesound Node (130 latest version) or iFi......either $600 or less, I use the Node. Get a reasonable USB cable, I highly recommend a Supra USB cable.

Check eBay for Supra USB cables and should find the 2.0 version for about $55, or better yet the Excalibur for about $140.....IMO the best value in USB cables....only buy from Zendada who is the official importer

Check out final touch audio , they use a special copper with naturally accruing silver and some specs ofGold in the metal and then pounded into thickness 

it sounds very analog like and natural , Lampizator audio Carry  them 

the Callisto model  look it up many excellent reviews.

“Don’t pay attention to those whose only answer is to buy a streamer. Using a PC with an audio only…..”

In a way this is true in that all streaming solutions are computers.  Of course, the better sounding streamers isolate from Ethernet noise, minimize internal noise from the computer segment, have really precise clocks and galvanically isolate the USB.  Some do not favor usb due to induced noise caused by the power within the cable itself.  One big difference is the quality of the power supply.

On a more serious note, many vendors have a thirty or sixty day trial period. You can do the A/B test and decide what works best. The problem is that better usually requires more money and that curve is not linear.
