Upgraded my Belkin Gold to a Wireworld Chroma, noticed a slight improvement in the bass region. Not much/any reviews available on this relatively inexpensive usb cable. I refused to believe for a long long time. Been in the hobby long enough, to realize that cables do matter, unfortunately. I really really wish they did not, but turns out every goddamn cable in the chain matters.. some more then others. Power, interconnect, digital, and headphone cables.. so annoying. To make it worse, they matter more or less depending on the gear they are hooked to. Some gear is better then others at eliminating differences, some gear does not resolve enough to hear it, though that barrier is quickly coming down in recent years, as much better audio gear trickles to the mainstream. In large part thanks to Objective, Schiit, Fiio..
Also aftermarket power cords are a pain in the ass, heavy, unwieldly, difficult to plug in, nothing like plugging a garden hose into your 1 lb amp. This alone has caused me to "put my head in the sand" for various parts of my time in the hobby. Eventually i'll try them again and have to admit they are different. One of my favorite power cords is so stiff the thing can walk around on it's own, standing upright like a cobra.
At least we have more options now that are affordable. Like Pangea.. I will never own 200$ interconnects or a 300$ usb cable. What I will do is DIY or high price/performance parts that a less then 100$, preferably less then 50$.
