This is the third time in two days, but I would be remiss if I didn't say anything. I took a chance on a USB from Supra Cables in Sweden. They make every kind of cable an audiophile would desire. You can find them on Ebay. I spent $50 for 1 meter. I had no idea of how much HF noise I had on my ferrite beaded USB! In fact I just bought a iFi iSilencer+ USB flash drive and the cable made a bigger improvement in noise suppression. It just is brimming with quantity and for only $50. This is the companies website, but they don't make any sales. They do explain exactly why their cables are so good.
