Speaker cables - Accessories

To achieve the best possible sound, it is crucial that the amplifier has a firm grip on the speakers. In addition to activating the membranes to make them vibrate, it must also be able to dampen them effectively. One measure of this is the amplifier’s damping factor. The speakers’ actual damping factor is significantly influenced by the quality of the speaker cables and connecting bridges of the bi-wiring terminals. The original bridges often consist of simple stamped sheet metal parts of inferior quality. The new in-akustik AIR High End Bi-Wire Jumpers are based on the technologies, findings and materials of the renowned LS-1205 AIR, LS-2405 AIR and LS-4005 AIR speaker cables. If bi-wiring is not an option, these high-end bi-wire jumpers offer an excellent alternative to the often inferior metal bridges on the speaker terminals. They ensure an even and controlled signal distribution, which is perfectly harmonized with the respective speaker cable.

To get closer to the pinnacle of audiophile perfection, we also carefully examined the conductor material. Copper in the right purity is itself already an excellent conductor, but a superconductor with no ohmic resistance to the current would be simply perfect. The material’s superconducting properties, however, require extremely low temperatures of at least -70 degrees. Under realistic conditions, silver is currently the most conductive material. With a conductivity of 61.35 S/m (siemens per meter), it outperforms copper by around six percent. Many manufacturers only use silver-plated conductors, which over time can seem, “bright”, “metallic” and even, “annoying”. We, on the other hand, use pure silver, which has a far more neutral sound. Due to the higher drift speed of the electrons, our pure silver cable delivers a more penetrating and sumptuous sound performance across all frequency ranges. On the other hand of course, silver is about one hundred times more expensive than copper.

The Referenz high-end bi-wire bridge, based on the LS-1002 and the Referenz spade lug KS-60. Concentric copper is used in the conductor structure, where each wire has a precisely defined position within the conductor. This structure ensures even signal transmission for crystal-clear audio reproduction. Under normal conditions, the copper used as conductor material is considered to be one of the next-best electrical conductors after silver. Compared to cheap CCA (Copper Coated Aluminum), copper has a significantly better conductivity and is also mechanically more resilient.

High-end and hi-fi systems are a combination of high-precision and intricately made devices. Perfectly attuned to each other, they allow music to be played back in outstanding quality. To ensure that all components can function flawlessly, they need to be kept free of interference to the greatest extent possible, just like high precision measuring equipment does. The same also applies for the connection cables. Interference is caused in a number of different ways. Along with typical electromagnetic interference, which can, for example, be minimised by using good shielding, mechanical vibrations and shocks also have an impact on the playback quality. Added to this are the effects of capacitive coupling between conductors and floors, which affect loudspeakers cables in particular. The conductors form unwanted capacitance, not just in interplay with each other, but also with other surfaces in the immediate surroundings. A good way to counteract this is by increasing the distance to the surfaces. As a rule, a few centimetres suffice. Vibrations are caused in different ways and they can be transmitted by structure-borne and air-borne noise. Structure-borne noise refers to vibrations that are exhibited by a body, such as the housing of a device. An example of this is the loudspeaker box. The membranes of the speakers are stimulated, making them vibrate. However, as the membranes feature a mechanical connection with the loudspeaker housing, they also transfer vibrations to the housing. The vibrations will be stronger or weaker according to the housing weight and the insulation. The vibrations are also transferred to the surface on which the loudspeakers are placed, this being the floor. Two things now occur. On the one hand, the floor emits some of the structure-borne energy as airborne sound (resulting in the typical droning noise), while on the other hand, the structure-borne noise is transferred, for example, to the cable placed on the floor. More about the effects of this later on. Airborne sound refers to vibrations that are transferred through the air and that are audible for humans (with the exception of infrasound and ultrasound). The primary purpose of a hi-fi system is to produce sound. However, airborne noise not only stimulates the eardrum, but also acts on all other surfaces it reaches. This causes the walls, floors and other surfaces, and ultimately the hi-fi components and cables, to vibrate as well. The combination of airborne and structure-borne noise not only causes glasses in a display case to vibrate mechanically, but all components, including the cable used for a hi-fi signal chain, as well. Experiments have shown that the sound from the components and from the cables is impaired by the vibrations. One reason for this is, for example, the capacity values of components in relation to each other, which constantly change due to the vibrations. In order to minimise these so-called microphonic effects, the components must be isolated from the surface on which they are placed. This can be done by using the Reference High Tech Gel Absorber, for example, for appliances and loudspeakers. Their core contains a special gel, which physically converts the vibrations into heat. The Reference Cable Bases have been developed specifically for cables. Their base also contains a special gel, along with natural rubber strips, in which the cables can float freely. Along with absorbing the vibrations, the Reference Cable Bases also keep the cables at a distance to the floor. This reduces unwanted capacitances and reduces the effects on the electronics.

High-end and hi-fi systems are a combination of high-precision and filigree devices. Perfectly coordinated, they are capable of reproducing music in outstanding quality. However, in order for the components to work perfectly, they must be kept as free from interference as possible, just like high-precision measuring instruments. The same applies to the connection cables. However, interference can occur in many different ways. In addition to the typical electromagnetic interference, which can be minimized by good shielding, for example, mechanical vibrations and shocks also affect playback quality. The Referenz cable bases have been specially developed for cables. They also have a special gel incorporated in their base and additional natural rubber bands to accommodate the freely suspended cables. As well as absorbing vibrations, the Referenz cable bases also keep the cable at a distance from the floor, reducing unwanted capacitance and the impact on the electronics.

The angled shape of the new BFA-103 banana plug relieves the strain on the contact sleeve and the device socket. This also allows heavy high-end cables to be connected without damaging the plug or the connection terminals on the devices. In addition, the angled cable routing saves space behind the devices and speakers. The body of the plug consists of a solid socket with two hex screws and can accommodate cables with a cross-section of up to 10 mm² or a diameter of up to 7.5 mm. All contact elements are coated with rhodium and guarantee long-lasting low contact resistance.

With the BFA bananas, we have developed a connection option for loudspeaker cables that complies with the strict provisions of the BFA standard (British Federation of Audio). The cable holder and the plug pin are made from a single piece, which prevents contact resistance. Suitable for in-akustik reference speaker cables and all high-end speaker cables with a cross-section of up to 10 mm². All contact elements are coated with rhodium and guarantee long-lasting low contact resistance.
