Key Features
- Perfect-Surface Silver (PSS) Conductors: Solid 100% PSS offers ultra-low distortion and maximum signal fidelity.
- Foamed-Polyethylene Insulation: Minimises energy absorption for tighter bass and sharper transient response.
- Carbon-Based 3-Layer Noise-Dissipation System (NDS): Shields against RF interference, preserving a black background and extended dynamic range.
- Dielectric-Bias System (DBS): Reduces energy storage and non-linear time delay for improved timing and resolution.
- Precision Direct-Silver Plated Terminations: Ensures a low-resistance, low-distortion connection with optimally formulated AQ solder.
Performance and Sound Quality
In critical listening sessions, the Diamond USB cable reveals hidden textures and micro-details, transforming digital files into immersive soundscapes. The combination of PSS conductors and DBS delivers a crystalline midrange with lifelike vocals, while the foamed-polyethylene insulation keeps low frequencies tight and impactful. High frequencies soar with minimal glare, thanks to the cable’s superior damping of RF noise.

It’s ideal for rig owners who demand transparency, dynamic contrast and a truly silent background.
