Tuesday, while installing the new DAC, I noticed that the coaxial cable was skinned down to the shielding, so I decided to replace it. I bought a $5 cable from Amazon, which arrived today, I installed it with no regards to any directional markings (if there was any) and without any burn in, just started to use it. I was absolutely floored, it works perfectly. Because of the flat shipping rate, I ordered 5 of them, so a total of $32.
