As with everything, you start out as a skeptic and with an open mind you are able to stumble across pieces of equipment that you can't believe you went with-out. After trying a few USB cables I came across the Nordost Blue Heaven USB. This was the first USB cable that actually made an improvement in my system instead of just sounding slightly different. I then decided to go all out and get the next step up.. the Nordost Heimdall 2 USB. This thing made as much, if not more of an improvement then a power cable or interconnect. But the question is WHY?
