The best USB I've heard close to this price is the Laboga Emerald. It's not the easiest to source, and judging by the absence of mentions on this forum, probably doubly so in the States.
Of all the USB cables I trialled it's the warmest, most analog and most musical I heard. I ended up, however, with the FTA Sinope as it's similar in character but just better. And 3 times the price.
The Emerald deserves more exposure as it really is excellent.
