Description
HiDiamond Diamond HID USB it is a digital cable designed for those who understand that, in high-end audio, data transmission also matters. It is not a simple USB: it is a cable designed specifically to optimise the connection between streamer, computer and DAC, reducing interference and preserving signal integrity.
Manufactured by HiDiamond, incorporates its own technology 4VRC©, with copper treated four times to minimise inductance, capacitance and resistance. The result is a more stable, clean and coherent transfer, designed for demanding systems.
A serious, well-made and durable cable, in the mould of those who prefer to invest in solid solutions rather than empty promises.
✨ Key features
-
✔️ Gold-plated metal connectors for maximum reliability
-
✔️ Pure copper conductors with 4VRC© technology
-
✔️ Double shielding against RF interference
-
✔️ Dual ferrite filter for EMI reduction
-
✔️ Linear transmission with very low loss
-
✔️ Robust and long-lasting construction
-
✔️ Optimised length: 1.8 metres
Designed specifically for use with DACs and high-fidelity systems, where electrical stability and isolation are paramount.
🔊 What does it bring to the sound?
In a well-tuned system, the Diamond HID USB contributes to:
-
Greater background cleanliness
-
Best spatial approach
-
More naturalness in doorbells
-
Removal of digital corns
-
Overall sense of greater coherence
Do not “colour” the sound: he orders it.

🏁 Conclusion Lyric Audio
The HiDiamond Diamond HID USB is a digital cable honest, well-made and technically sound.




4VRC Technology ©: means the adoption, as a conductor, of four-times-annealed copper, instead of the 2VRC used by other competing companies. This technology allows a higher purity to be achieved than that obtained by normal annealing (twice). It also means that the braid / capillary is processed at different temperatures four times instead of two. The purity of the cable source material is decisive.
