为什么数字线材对声音的提升有帮助呢?我们写了封信给Nordost，希望他们给我们用一个比较简单的方式来向大众解释为甚么USB线材与网络线材是有帮助的，这是来自 Nordost的回复:I think the key take away for conversationsabout any digital cable is that it isn't one's and zero's that are beingtransmitted. It's analog square wavesthat represent those one's and zero's. Because of that just like with any other cable the integrity of thesignal within the cable is impacted by everything from length， dielectric，conductor material， conductor gauge， etc.
