Van den Hul The First RCA 1.5m
Overview
In 1993, A.J. van den Hul introduced the first audio interconnect cable without a metal conductor. More than thirty years later, the The First range has expanded with several variations. The Metal Screen version retains the original architecture based on Linear Structured Carbon (LSC) and adds a dense metal shield to meet the most demanding installation requirements, where ground currents and electromagnetic interference pose recurring problems.
A linear-structure carbon conductor
The core of the cable is based on the patented Linear Structured Carbon technology. The central conductor consists of 12,000 carbon strands with an individual diameter of 7 microns, each insulated individually. This fiber‑by‑fiber insulation prevents electrons from flowing laterally from one strand to another: the signal propagates in a strictly unidirectional way, which reduces distortion phenomena related to interactions between conductors.
Carbon offers thermal, chemical, and mechanical stability that metals cannot achieve. Whereas copper or silver gradually oxidize and degrade over time, structured carbon retains its electrical and acoustic properties year after year. Van den Hul also points out that The First can be recycled at the end of its life: the material is remelted and reused as an extrusion layer on other cables from the brand.
Double shielding and minimal ground resistance
The Metal Screen version differs from the The First and The First Ultimate models by the addition of an external metal braid made of silver‑plated OFC Matched Crystal® copper, surrounding the existing LSC shielding layer. This double shield—carbon saturated on one side, high‑purity metal on the other—reduces shielding resistance to 0.0049 Ω/m, a value significantly lower than that of The First Ultimate (around 4.8 Ω/m) and the original The First (around 14 Ω/m).
This extremely low resistance is especially meaningful with tube amplifiers, which are often prone to parasitic ground currents that manifest as hiss or hum. It also proves valuable in electrically noisy environments, near transformers, switching power supplies, or IT equipment.
Low‑level signals and long runs
The Dutch manufacturer particularly recommends The First Metal Screen for carrying low‑amplitude signals. The connection between a phono cartridge and a preamplifier, or the link from a microphone or an electric musical instrument, benefits from the interference immunity provided by this cable. The measured capacitance (61 pF/m) remains moderate, limiting high‑frequency attenuation even over significant lengths.
Unlike the fully carbon versions, The First Metal Screen can be ordered in lengths greater than 1.5 meters. This option enables installation configurations that are difficult to achieve with cables that are more susceptible to interference over long distances.
Construction and finish
The outer diameter is 7.5 mm, with a central conductor cross‑section of 1.0 mm. The peach‑colored Hulliflex jacket provides durable mechanical protection and good resistance to surrounding chemical agents. This halogen‑free material, adopted by Van den Hul as early as 1990, prevents the release of harmful substances in case of combustion or disposal.
Factory‑fitted C‑8.0‑type RCA connectors are used. Van den Hul does not offer this cable on a reel for DIY assembly: connecting the carbon fibers to the metal pins requires specific expertise in order to avoid internal reflection issues at the terminations.

Frequently Asked Questions
Does the audio signal travel through the metal shielding?
No. The central conductor is exclusively carbon; the signal never passes through the metal. The silver braid is used solely for shielding and ground return, protecting the signal from external interference without taking part in its transmission.
Is this cable suitable for turntables with low‑output MC cartridges?
Van den Hul recommends it primarily for MM cartridges and high‑output MC cartridges. Very low‑output MC cartridges generally require a dedicated phono cable with impedance and capacitance optimized for that type of source.
Can The First Metal Screen be used as a digital SPDIF cable?
Yes. The 75 Ω characteristic impedance and the cable’s low capacitance make it suitable for carrying coaxial digital signals between a CD player, DAC, or streamer.
What is the difference compared with The First Ultimate?
The First Ultimate uses an all‑carbon shield (six LSC layers, i.e. 114,000 strands), with no metal. Its higher shielding resistance can cause a slight hiss with some tube amplifiers. The First Metal Screen solves this issue thanks to its metal braid, at the cost of a hybrid construction.
