Posts like yours are what is confusing people on the issue... because they are utter nonsense.
With a digital cable, either it transfers the data, or it has gaps in. Little dropouts. There is NO alternative. A cheap cable CANNOT sound muddy or distorted.
How many times do many different users here have to say this, before people will understand? I think you all need to make yourselves a nice hot drink, and spend the afternoon reading up on how digital signals in general work, with regards to USB/coax etc etc.
I took the trouble to take the brand new stock USB cable that came with my DAC1 USB from the plastic bag to compare with my Kimber hoping that I can sell the Kimber for a few bucks and use the freebie. Unfortunately, after a brief listening session of familiar music, I find the Kimber to be better. It wasn't night and day. I'd actually call it a 0.5% difference. However, for the money, it's worth it. And I didn't have to listen particularly hard to find a difference. I hate it when I have to listen hard to distinguish any difference; it distracts from the music. But what bothers me more ... see first paragraph.
