For Referenz Selection cables, the focus is on neutrality in addition to technical finesse. Sounds are reproduced unaltered. As with the LS-1603. It controls all facets of the sound spectrum: from the subtle symbol clash of a jazz percussionist to the sententious voice of a female soul singer to the roaring final chord of a symphony orchestra. The basis for this is the specially developed high-speed waveguide technology. Oxygen-free copper (OFC) wires are wrapped around a polyethylene core and provided with the proven DUO-PE II insulation. The LS-1603 has 16 of these high-speed waveguides, which are finely tuned to each other and stranded in groups around a polyethylene support (16-fold multicore). The PE network jacket proved itself already in the second Referenz generation. A major reason why the third generation of Referenz speaker cables is benefiting from this technology.
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.
As the frequency rises, the signal increasingly flows on the conductor surface. The higher the frequency, the lower the effective cross-section, and the greater the resistance. The cable sounds “bass-heavy”. The conductors from the LS-1603 have a core made of polyethylene. In this way a circular waveguide is formed and the actual cross-section used is the same for all sound frequencies. The result: a homogeneous, balanced speaker cable with a wide-ranging sound spectrum.
The rhodium surface treatment is extremely durable. The contact surfaces and the screw connection are manufactured from a single piece, allowing contact resistance to be avoided. The spade changes shape. The contact surface, which is slitted on the side, changes to a concave shape when the screw connections are tightened, thus preventing the spade lug from sliding out.
This BFA 103 plug meets the strict requirements of the BFA standard (British Federation of Audio). The cable receptacle and the plug are constructed in one piece so that contact resistance can be avoided. The surface coating of rhodium is extremely durable.
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.
