Digital Coax 1.5m

[ada]

First of all, I don't think there is a difference in 75 ohm digital cables in the 1.5 meter range. But if there is, the sound difference is not only due to the background noise, but also the impact of the medium, which is the cable itself. If someone says that one cable makes a difference to another, I assume that he doesn't pay 10 times more just to have the background noise distributed better between the amplifiers, but rather he expects better connectivity. If that's not the case, you don't need to read the rest

Secondly, yes, the signal is 100% stereo, but not bi-directional. It's just one direction from the one with the input to the one without. (I don't say master or slave because the input could be on the slave).

What we are discussing here is;

1. The signal comes from the source to the head unit
2. The head unit converts the signal into a low-level PCM signal that will be ready to be sent to the DACs
3. The head unit receives the signal directly from the internal components
4. The second unit receives the signal from the link cable!
5. The music is played in dual mono mode

In this setup, the difference in the medium (cable) only affects the sound heard on the second unit. Yes, the background noise is bi-directional, but we are not just talking about noise, but about the cable making a difference to the digital signal and that only applies to the sound from the second amplifier.
