Product information "LS-40"

Inductance is a critical behavioral feature of a cable, causing resistance to the signal flow, rising with the frequency. Multicore architectures, such as that of the LS-40, reduce this effect and bring more precision and punch to the sound.

The conductors of the LS-40 are made of high-purity copper. Under normal conditions, copper is the next-best electrical conductor after silver. Compared to cheap CCA (Copper Coated Aluminum) in particular, copper has a significantly better conductivity and is also mechanically more resilient.

The stranded wire design is a tried and tested conductor design in the hi-fi sector. Each conductor consists of 50 x 0.25 mm strands that are "twisted" together. The advantage of this design lies in the economical method of production and the mechanical flexibility, which increases with smaller diameters of the individual wires.

The conductor cross-section of 2x5.0 mm² is the foundation for a dynamic and powerful sound. The polyethylene (PE) insulation of the LS-40 has very good electrical properties. Compared to PVC, it halves the annoying battery-like capacitance of cables. The reproduction gains in brilliance and spatial quality.

The PE network jacket protects against mechanical damage and serves as additional insulation.

Description

Inductance is a critical behavioral feature of a cable, causing resistance to the signal flow, rising with the frequency. Multicore architectures, such as that of the LS-40, reduce this effect and bring more precision and punch to the sound.

The conductors of the LS-40 are made of high-purity copper. Under normal conditions, copper is the next-best electrical conductor after silver. Compared to cheap CCA (Copper Coated Aluminum) in particular, copper has a significantly better conductivity and is also mechanically more resilient.

The LS-104 is an excellent entry-level model to the Micro AIR series. It already stands out clearly from standard cables and demonstrates the acoustic potential of this technology. Sensitive amplifiers in particular harmonize excellently with this cable. The Referenz LS-104 Micro AIR provides an open and relaxed sound. It is also available with BFA bananas or spade lugs and as an Easy Plug version.

The Referenz LS-1002 has 4 conductors, each with 37 concentrically stranded wires. The cores are arranged in a double symmetrical fashion and specifically configured in the CC-297 design to keep the inductance low and the resistance linear. The larger cable cross-section ensures excellent and controlled bass reproduction and a high level of efficiency. Polyethylene (PE) already boasts excellent electrical properties for audio, video and digital cables. The foaming process creates an air content in this dielectric, which further diminishes any annoying battery-like cable capacitance. The reproduction gains even greater brilliance and spatiality. A layer of solid PE protects the foamed PE from mechanical influences.

Inductance is a critical behavioral feature of a cable, causing resistance to the signal flow, rising with the frequency. Multicore architectures, such as that of the LS-1002, reduce this effect and bring more precision and punch to the sound. With conventionally stranded wires, the individual strands run chaotically through the conductor. This leads to undefined contact points, which can result in degraded signal transmission. In contrast to this, each wire in the Concentric Copper structures has a precisely defined position within the conductor. This enables homogeneous signal transmission and ensures crystal-clear audio reproduction.
