Hi, I am interested in making some diy cables, but have stumbled on a possible cause for concern. Does anyone know what reflections and feedback means with regards to cables? I understand that digital cables have to be a minimum length. Also some interconnects have to be at least one meter in length such as chord signatures. Does anyone know if this also applies to mains cables? I am looking to make four or five 0.6m or 0.75m lenghts from some Nordost Vishnus, if this is possible it could work out to be "relativly!" cost effective.
