MARC Copper Technology - [super] conductors - Ricable

In 2015 we introduced AM-RCC conductors into our Power cables, and the result was outstanding. Since then we have been working on further improvement of our conductors, because although the result was already very good, we saw room for significant improvement.

These studies resulted in the new conductor MARC©, an acronym for Multicore Annealed Ricable Conductor, which characterizes the entire production Magnus, Dedalus and Invictus.

The improvements made made it possible to produce a copper conductor with 7N purity (99.99999%) that is more malleable than its predecessor, due to the reduction of grains per meter by 25% compared to AM-RCC. This production implementation allowed strands to be produced that was smoother on the surface, more ductile and smaller in diameter.

The benefits of this are as follows:

1. Greater quantity of raw material:
The conductor wires are thinner and in greater quantity for the same cross section, and as a result, with the same conductor area, we have a greater amount of copper

2. Skin Effect Abatement:
By increasing the number of conductor wires and reducing the grains of processed copper resulting in surface compaction, there is a substantial reduction in the skin effect, which in audio applications is one of the major causes of acoustic signal degradation.

3. Lowering Resistance:
Another effect of increasing the decrease in wire diameter, with the resulting increase in the amount of copper, the electrical resistance has also been reduced considerably.

4. Flexibility:
MARC© Copper, in addition to acoustic and electrical benefits, has improved cable flexibility by up to 70% compared to OFC Copper.

5. Acoustics:
The new MARC© processing, combined with the other innovations introduced, produces in the sound greater transparency, better detail, and a more characterized Soundstage, all while maintaining the neutrality that has always distinguished our production.
