In “cabling ” too, there’s a priority of intervention.

Assuming that the quality of all the cables in a given system is homogeneous,
its’ always better to start from the power cord of a digital source.

A good power cord, will be always perceived as a dramatic improvement
in terms of quality; further cables connected to the equipments, such as
interconnects or speaker cables, will affect the system with a less increase
in overall quality.
