I thank you for choosing ‘the standard series’ of cables to upgrade your existing system. And, I am happy to work with you on price reduction, when you decide to upgrade again. These are the terms used to describe the cables.

BANDWIDTH 

Bandwidth is the frequency scope of transmission. The bandwidth of a typical audio signal ranges from 20Hz to 20 kHz. A narrower bandwidth transmits fewer frequencies. A telephone typically transmits around 300 Hz to 3 kHz, and a larger one will carry more. DVB-S (satellite) systems currently use bandwidths of more than 2 GHz

IMPEDANCE (75 OHMS/110 OHMS) 

The wave resistance, or impedance, is a crucial prominent figure for cables, calculated from the ratio of inductivity to capacity. 

CAPACITANCE 

Capacitance is the measure of the capacity to store electrical charges. However, cables should be able to transmit 100% of the signal without temporarily storing it. Therefore, the less capacitance a wire has, the better.

INDUCTIVITY 

Each conductor passing information forms a magnetic field around it. If current changes, the strength of the magnetic field also changes in an inductive current which counteracts the replacement of current in the conductor. A frequency-dependent resistance develops (also called inductive resistance), which harms the transmission. Exclusive designs reduce the inductivity of a cable. 

INSULATION (DIELECTRIC)

The conductors are covered in a non-conductive material to protect against short circuits, corrosion and damage. However, these materials store energy (capacitance), which is undesirable in audio and video cables. 

When serially transmitting A/V data, cable properties affect these impulse durations so that data is not received correctly. In pronounced jitters, the D/A converter has to correct the error frequently, and consequently, the quality of playback for pictures and sound suffers. 

The weakening of a signal transferred in a cable is called damping and specified in dB (decibels). I.e. it is a measure of signal loss. The damping of an audio cable depends on the frequency. This specification is essential for planning antenna cables for antenna systems. It should not be confused with the shielding dimension and specified in dB.

The data rate specifies how many data units (bits) are transferring per second. The maximum data rate with an HDMI 2.0 interface is up to 18 Gbps. That is 18 billion bits or 2.25 billion characters per second (8 bits = 1 byte). The Range in 2021

POLYETHENE (PE) 

PE is a high-quality insulating material (dielectric) that is ideal as an insulator. It reduces the capacitance of a cable by a factor of two compared with PVC (polyvinylchloride). As a result, the electrical loss of PE is also low.

SHIELDING

Protection against electromagnetic interference, cables are shielded with one or more layers (e.g. a wire braid or aluminium coated Mylar film). The impact of the screening is measured in dB and describes the reduction of any interference. 

SILVER-PLATING

High frequencies are mainly transmitting on the surface of the conductor (skin effect). As silver is the best conductor, the high rates are transmitted better via silver-plated conductors. On audio and speaker cables, silver-plated cables boost the high-frequency range. On HDMI connections, the silver-plated conductors also ensure optimum signal transfer, even on long audio lines. The Range in 2021

GOLD-PLATED CONTACTS

The 24-carat gold-plated plug contacts considerably reduce contact resistance and transfer signals optimally. The quality of the connection shows in the contact resistance. Poor connections have high contact resistance and cause signal losses. Unique surface treatments such as gold-plating contact surface considerably reduce resistance, improve the links and, therefore, the sound and picture quality. 

SOLID CONDUCTORS

The many fine wires are bundled on standard cables, meaning the electrons can “jump “from one wire to another. The signals travel for different lengths of time, and fast impulses are “braked”. Solid conductors prevent this by providing the exact transit times and precise, sharp contours. Solid conductors also offer another benefit for digital and video quality: The smooth surface allows the impedance to be precisely adjusted and high signal frequencies transmitted correctly. The Range in 2021

Loudspeaker cables with the wires arranged in the same direction tend to get twisted. They are making laying the cable and installation difficult. Lines with S/Z stranding have wires with opposite stranding to avoid this effect. Best Audiophile Cables Online

As the HDMI interface sound and picture content is available in absolutely perfect resolution, the film and software industry have instructed that data is released only as copy-proof. 

TWISTED PAIR

With symmetrically designed cables, two identical wires are used for the initial and return conductors. And counteracts the level of electromagnetic interference and provides exceptionally high immunity to interference. Also, separate shielding protects the signal.

Standard series

The standard series is a really excellent series of cables to start out with. I have kept the price to the minimum level, but there are always discounts available. And, if you need help with pricing please let me know. I want to tell you that, you are now on the road to better sound and performance. And, now, you will hear many things in your music, you were never aware of.
