The Classic Legend MkII 380 USB Cable applies Siltech’s proprietary G9 silver-gold conductor technology to digital audio connections using the USB interface. As part of the 380 Series, it introduces a dedicated four-core architecture developed for connecting compatible USB audio components.
At its core are four conductors made from Siltech’s pure silver-gold alloy G9. Siltech’s proprietary silver-gold metallurgy forms the conductor foundation of the Classic Legend MkII family and is applied here specifically to the requirements of USB signal transmission.
The four G9 silver-gold cores use a twisted-pair construction, providing the dedicated cable geometry of the 380 USB.
Signal protection is an important part of the 380 USB architecture. Special Wide-range Shielding is combined with Carbon-Infused Shielding to create a carefully controlled environment around the signal path and provide protection from unwanted electrical influence.
This combination distinguishes the 380 USB within the Classic Legend MkII range. Rather than sharing the architecture of the 380D Digital Cable, the USB model uses its own four-core construction and dedicated combination of shielding technologies for its specific digital application.
The Classic Legend MkII 380 USB Cable brings together G9 silver-gold metallurgy, four-core twisted-pair construction and advanced dual shielding in a purpose-built solution for high-performance USB audio connections.
A new chapter in the Legend
The Classic Legend MKII Series introduces four distinct ranges within the collection: 280 MKII, 380 MKII, 680 MKII, and 880 MKII. The lineup includes interconnects, speaker cables, power cables, and digital cables, each engineered around the same core philosophy: preserving the purity and integrity of the musical signal with the least possible interference.
For the first time, the Classic Legend family now begins with the new 280 Series, bringing Siltech’s renowned G9 silver-gold conductor technology to a more accessible starting point within the range. Across the entire MKII lineup, Siltech introduces a new generation of internal shielding and insulation technologies, including advanced carbon-based shielding and refined air-filled construction techniques designed to reduce EMI and RFI influence while maintaining openness, speed, and natural musical flow.
Building upon the strengths of the original Classic Legend Series, the MKII generation delivers further improvements in transparency, timing precision, spatial realism, and low-noise performance. The combination of proprietary silver-gold metallurgy, improved signal protection, and carefully optimized cable geometry allows the series to reveal more detail and musical expression without adding artificial character or exaggeration.
The result is a presentation that feels quieter, more stable, and effortlessly balanced, with enhanced stereo imaging, refined dynamics, and a natural sense of scale throughout the listening experience. Developed from decades of Siltech research and engineering expertise, Classic Legend MKII continues the philosophy that true cable performance comes not from coloration, but from preserving the signal exactly as intended.
G9 Silver-Gold Technology
At the heart of the Classic Legend MKII Series lies Siltech’s proprietary G9 silver-gold conductor technology, the result of decades of continuous research into signal transmission, metallurgy and long-term performance stability.
Silver remains the most conductive metal available for audio signal transmission, valued for its exceptional speed, detail retrieval, and low resistance characteristics. Within Siltech’s G9 conductor platform, high-purity silver is combined with carefully controlled traces of gold to stabilize the crystal structure of the conductor itself. This helps reduce microscopic imperfections and electrical distortion while preserving the natural openness and precision that define the Siltech sound.
In Classic Legend MKII, G9 silver-gold conductors are now implemented throughout the entire range, including the newly introduced 280 Series. This creates a fully unified Classic Legend family built around the same core Siltech metallurgy philosophy.
Combined with the new carbon-based shielding and advanced air-filled insulation construction introduced in MKII, the G9 conductor platform allows the signal to travel through a quieter and more stable electrical environment. The result is improved transparency, lower noise, greater timing accuracy, and a more natural musical presentation across the entire series.
Rather than emphasizing the cable itself, G9 technology is designed to preserve what matters most: the integrity, emotion, and realism of the original recording.
Insulation and Shielding
Classic Legend MKII introduces a new generation of internal insulation and shielding technology developed to create a quieter, more stable environment around the signal path. Rather than focusing on cosmetic changes, the MKII evolution centers on improving the electrical behavior inside the cable itself.
One of the most important advancements is the introduction of carbon-based shielding. Developed through extensive Siltech Group research into electromagnetic noise control, this shielding approach is designed to absorb EMI and RFI interference while maintaining the openness, speed, and natural musical flow for which Siltech cables are known. The goal is not simply stronger shielding, but smarter shielding that protects the signal without restricting it.
Complementing this is a refined air-filled insulation construction. By increasing the role of air around the conductor, one of the most effective natural dielectrics, Classic Legend MKII reduces the electrical influence of surrounding materials and helps maintain low capacitance, stable signal behavior, and improved timing accuracy.
Together, these technologies work as one complete cable architecture alongside Siltech’s proprietary G9 silver-gold conductors. The result is lower noise, greater transparency, improved spatial precision, and a more effortless musical presentation with exceptional balance and realism across the entire Classic Legend MKII Series.
