iFi Audio SilentPower Pulsar USB Cable & Power Conditioner

iFi Audio Pulsar USB

Unlock the full potential of your digital audio system with the Pulsar USB — a precision-engineered cable and conditioner that redefines USB audio performance. Unlike generic USB cables that compromise sound with poor shielding and noise-prone construction, the Pulsar delivers pristine signal integrity through galvanic isolation, targeted Active Noise Cancellation, and audiophile-grade materials. Built with high-purity OFHC copper, advanced quad shielding, and stable 90Ω impedance, it ensures clean power and uncompromised high-speed data transmission. Whether you're connecting a DAC, streamer, or audio interface, the Pulsar USB delivers nothing but the music — fast, pure, and transparent.

What It’s Good At

• Eliminating USB-borne noise with galvanic isolation between source and audio system
• Delivering cleaner USB power using Active Noise Cancellation for lower perceived hash and glare
• Preserving detail and timing by keeping power and data paths fully isolated
• Supporting high-resolution playback and fast transfers with USB 3.1 up to 10Gbps
• Improving system “black background” and clarity by suppressing EMI/RFI and ground-loop effects
• Providing a premium build for audio setups with quad shielding and audiophile-grade conductors

Q&A Section

Q: What makes the Pulsar USB better than a regular USB cable?
A: The Pulsar uses galvanic isolation, active noise cancellation, and audiophile-grade materials to remove noise and preserve high-resolution audio detail.

Q: Does it improve sound quality with all DACs?
A: Yes, it's compatible with all USB DACs and enhances any system by delivering cleaner power and a more accurate digital signal.

Q: Is this only for USB-C devices?
A: No, it includes USB-C to USB-A and USB-B adapters, making it compatible with a wide range of USB audio gear.

Q: How does the Active Noise Cancellation work?
A: It detects EMI/RFI noise on the power line and cancels it with an inverted signal, similar to how noise-canceling headphones work.

Q: Can I use it for both power and data?
A: Yes, the Pulsar transmits both clean 5V power and high-speed 10Gbps USB data.

Q: Is this a USB 2.0 or USB 3.1 cable?
A: It's USB 3.1 compatible and supports up to 10Gbps data speeds — 20 times faster than USB 2.0.

Q: How long is the cable?
A: The Pulsar USB cable is 1 metre long.

Q: Does it require special drivers or setup?
A: No, it’s a plug-and-play device — just connect it and enjoy instant improvements in sound quality.
