Generally the more you spend on a USB cable the better the sound so replace the Belkin.
The two most recent cables I used were the FTA Callisto and Sinope. There is a moderate price difference in the cables but the sound difference is huge!
Before that I used the original Network Acoustics Eno Ag and that way much better than the Curious Cable which was way better than a no name cable like yours.
I would suggest taking advantage of the Network Acoustics trial offer for their cable as well an Ethernet Filter if you don't already have one and if you can afford it one or more of their Ethernet cables. All it will cost you is the return shipping and your not likely to pay that after hearing the benefits.
Also realize that different USB cables have different sounds and sound different in different systems. Unfortunately you need to hear the cable in your system to know if it is to your liking or not.
I have an Innuos Statement and can only recommend the brand, and while the USB output is very good I have found the Ethernet out to be superior. I use a series of DDC's to get to a S/PDIF input for my DAC, verses a direct USB to USB connection.
