Equipped with the same basic technologies as the LS-1603, it also has the high-speed waveguide technology. The actually usable cross section of these circular waveguides remains constant for all sound frequencies. The result: an extremely homogeneous, balanced speaker cable with a wide-ranging sound spectrum.

"The testers anticipated improvements in the family – and were still surprised by the LS-1203. Here the sound demonstrated that the total of all the family's good genes was more than the sum of its parts." (Audiophile Magazine)

12-fold Multicore

The flow of current causes magnetic fields to be created in the cable, leading to a partial loss of power. High frequencies are slowed down – and time lag is created between low and high sound frequencies. The circular arrangement of several wires around the polyethylene support causes the magnetic fields of plus and minus conductors to overlap and neutralise each other. The high sound frequencies are transported unhindered and synchronously.

We have long set the bar very high in regard to quality, because cables and connections are extremely sensitive. Physical phenomena that arise during the transmission of signals can only be controlled with technical finesse and the best materials. For this reason all cables are manufactured in a German cable mill and finished by us in Ballrechten-Dottingen in elaborate manual work.
