Features & Specs
Galvanic isolation between source and audio system
Physically separates your USB source from your audio device to reduce ground-loop issues and block electrical noise that can blur detail and raise the noise floor.
Active Noise Cancellation on USB 5V power
Actively targets EMI/RFI riding on the power line by generating an inverse signal to cancel interference, helping deliver cleaner USB power to sensitive audio components.
USB 3.1 compatible up to 10Gbps
Supports high bandwidth for modern USB audio and high-resolution playback workflows, reducing the chance of bottlenecks when handling large files or demanding streams.
Quad shielding for interference rejection
Multiple shielding layers help protect the signal path from external noise sources commonly found around computers, routers, and switch-mode power supplies.
Heavy OFHC continuous cast copper silver matrix conductors
High-quality conductor materials are used to maintain strong conductivity and preserve signal integrity for transparent, true-to-source playback.
Stable 90Ω impedance (1% deviation)
Engineered impedance consistency helps reduce signal irregularities and supports cleaner transmission for a more refined, stable presentation.
