iFi SilentPower Pulsar USB Galvanically Isolated USB-C Cable with ANC
Best audiophile upgrade for eliminating digital noise in high-resolution audio setups.
Experience unparalleled sonic transparency with the iFi SilentPower Pulsar USB cable. Engineered to eliminate noise, it physically separates your audio system from the source, eradicating ground potential differences and RF interference. Proprietary Active Noise Cancellation (ANC) cleans the 5V USB power path, canceling EMI and RFI in the audible range. This USB 3.1 compatible cable supports up to 10Gbps transfer speeds, ensuring flawless high-resolution audio playback. Featuring high-purity OFHC copper conductors and four layers of shielding, it preserves signal integrity for true-to-source sound.

What customers say
Users overwhelmingly praise the iFi Pulsar cable for its profound impact on system noise, especially in high-resolution audio setups. The combination of Galvanic Isolation and Active Noise Cancellation technology delivers a significantly quieter background. This noise reduction sharpens micro-dynamics, improves transient response, and creates a wider, more layered soundstage. Listeners report that harsh digital artifacts are mitigated, resulting in a more natural and less fatiguing experience during long sessions. While the price is premium, most audiophiles agree the tangible sonic improvements fully justify the investment for optimizing sensitive digital components. Build quality also receives consistent positive feedback, reinforcing its status as a high-end accessory.
Know before you buy
Unlike standard cables, the Pulsar features built-in galvanic isolation and Active Noise Cancellation (ANC). These technologies physically separate your audio device from the source to eliminate electrical noise and ground loops that can degrade sound quality.
Yes, if your current setup suffers from audible noise, jitter, or interference from your computer's power supply. By cleaning the 5V USB power path and shielding the data signal, the Pulsar provides a cleaner, more transparent signal for your DAC to process.
Absolutely. The Pulsar is built to the USB 3.2 Gen 2 standard, supporting data transfer speeds up to 10Gbps. It is fully capable of handling demanding data tasks while maintaining its audio-focused noise reduction benefits.
No, the ANC circuitry is powered directly by the USB bus. It is an active component integrated into the cable design, so you can simply plug it in and use it like any other USB cable.
The Pulsar is compatible with any device that adheres to the USB 3.1 or 3.2 standards. It is designed primarily for high-resolution audio applications, such as connecting a computer to a high-end DAC or audio interface.
The integrated ANC technology is capable of reducing power line noise by up to 40dB. This specifically targets EMI and RFI interference within the audible range to ensure a quieter background for your music.
