Platinum Starlight 7 HDMI.
The Wireworld Platinum Starlight 7 HDMI represents the upper tier of the manufacturer’s Series 7 lineup, featuring a distinct conductor architecture and material selection for high-bandwidth digital transmission.
Platinum Starlight 7 is the upper HDMI model in Wireworld’s Series 7 range, identified by catalogue code PSH. It combines the company’s 24-conductor DNA Helix geometry with solid-silver conductors, Composilex 2 insulation and carbon-fibre connector housings. These are the period Series 7 specifications, separate from the later Platinum Starlight 48 model.
The conductor arrangement
The quoted 24 signal conductors describe the cable’s internal construction, rather than the physical contacts of the HDMI connector. Wireworld arranges layered flat conductors symmetrically and states that this geometry aims to channel electromagnetic signal energy and maximise transmission speed. Its stated fidelity benefits are the manufacturer’s claims for that arrangement.
The three upper Series 7 HDMI models share the 24-conductor DNA Helix specification, but use different conductor metals. Platinum Starlight 7 uses solid silver at 23 AWG; Silver Starlight 7 uses silver-clad oxygen-free copper, while Starlight 7 uses silver-plated oxygen-free copper. The material specification therefore distinguishes these models without changing the published conductor count.
Further down the same range, Ultraviolet 7, Chroma 7 and Island 7 use a 16-conductor Symmetricon arrangement. The catalogue therefore separates the HDMI range by geometry as well as conductor material. Series names alone do not describe the construction: the model designation identifies which arrangement and metal specification apply.
Insulation and connector construction
The company’s catalogue dates its beginnings to 1992 and describes founder David Salz’s work on Cable Comparators, intended to compare a cable with a direct connection between components. Wireworld presents DNA Helix and its composite insulation as results of that development approach. For Series 7, it specifically identifies Composilex 2 as the revised insulation, with the stated aim of reducing noise associated with conventional insulating materials.
The catalogue also specifies a shielded, isolated power conductor, separate from the signal paths, within a flat and flexible cable form. HD-Grip plugs complete the connection. The isolated conductor is part of the HDMI cable construction, rather than a separate external power supply or an active conversion stage.
Platinum Starlight 7 uses carbon-fibre connector housings, while Wireworld lists aluminium housings for Silver Starlight 7. The plug contacts themselves have silver and gold plating. Housing material, contact plating and the solid-silver signal conductors are separate specification choices, even though all three appear together in the description of the finished cable.
HDMI and I²S applications
Wireworld’s period catalogue states HDMI 2.0 / 4K capability for its listed lengths and includes Audio Return Channel in the HDMI features. The photographed cable’s length was not recorded, so the available catalogue lengths should not be treated as an identification of this particular example.
PS Audio’s DirectStream DAC manual explains that its I²S connector uses HDMI-style cabling to carry separate clock and data signals. This application is distinct from conventional HDMI audiovisual input, relying on specific pin assignments for digital audio transmission. PS Audio identifies its PerfectWave Transport as one compatible example.
For I²S use, the source and DAC must have compatible pin assignments. A passive HDMI cable does not convert standard HDMI video or audio signals into I²S, nor does it perform digital-to-analogue conversion or establish universal interoperability.
