During the development of the Sibelius loudspeaker we had to decide what cables to use to power them. And although we chose for 2 X 1,5mm, silver plated, low oxygen copper multi-strand for the short link between the drive unit and the rear terminal posts, we had to agree on the cable to use between amplifiers and cabinets. There can be no doubt that cables are in fact ‘components’ and they can (and do) have an influence on the sound; especially because the Sibelius loudspeaker is directly coupled to the output terminals of the amplifier. The results of our discussions was to go for a ‘neutral’ option by using readily available multi-strand copper. If we could get the sound exactly where we wanted it with ‘msc’ then this could form the basis from which our customers could fine tune their installations.
But there is more to a cable than just its primary conductor. There is also the question of the connectors and sheathing. For a start we wanted our cables to lie nice and flat on the floor and to have a matt black casing, so as not to detract or glisten in artificial light. In addition, because the Sibelius terminal posts are positioned relatively high up on the back of the cabinet (80cm from the floor, when on Sibelius stands), we wanted a clamp system to ensure they could not fall out or accidentally removed.
