The notion that a digital cable, including Ethernet and USB, can be susceptible to noise is often met with harsh criticism. If we then add fuel to this fire by further suggesting that this noise can cause an audible difference in our connected hi-fi, we are typically met with derision. Some people contend that for all intents and purposes, digital systems are noise-proof, the proof being bits are bits. Therefore there’s no way a digital cable can possibly make any difference when it comes to the sound coming out of our speakers. The fact that noise in digital systems including digital cables is a well-known problem outside the world of hi-fi doesn’t appear to make one bit of difference. Let’s see if we can separate the signal from the noise.
