The shorter the better? When talking of cables, this statement is often presented as an axiom, although after several experiments it is not even a theorem for me. Using the example of intercon cables (the same manufacturer and the same model), I can say that in most cases a cable 1 or 0.8 meters long sounded better than half a meter long. I suspect that the matter is in some "wave" nuances, but I would be happy to know the expert's opinion.
Where do cables upgrades have the most impact?
Assuming all existing cables in a system are atleast mid-grade (not junk), which cables/interconnects should be upgrade first and in what order? Where should one start?
