While capable of passing hi-res data at max resolution and allowing bit-perfect transfer, USB was not created specifically for audio. It carries both power and data. It is susceptible to electrical noise, for example, from the computer’s power supply. This has a negative effect on sound quality. Fear not! At iFi, we first banished these gremlins with the iSilencer3.0 and now, we’re making silence sound even better with the iSilencer.\nActive Noise Cancellation\nThe iSilencer+ removes electrical noise (including EMI/RFI) at source using iFi's Active Noise Cancellation II circuit. This process enables bit-perfect transfer of audio data to the DAC.\nSuperSpeed USB 3.0\n‘SuperSpeed’ USB 3.0 has a more exhaustive wiring specification which allows for a greater amount of audio transfer while still being backwards compatible. The units incorporate high-quality gold-plated connectors for optimal signal transfer.\nREbalance® the USB signal\nThe new iSilencer+ re-balances signals via iFi's REbalance technology, ensuring that the digital signal received by the DAC is identical to the original source, no matter which audio format is being played.\nSpecs\n\nCompatibility: Super-Speed USB 3.0 (backwards compatible with USB 2.0)\n\nRating: 5V (6.3V max.), 1A\n\nDimensions: 50 x 20 x 9mm (2.0\" x 0.8\" x 0.35\")\n\nWeight: 7g (0.25oz)\n\n\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-accessory-ifi-audio-silentpower-isilencer-usb-noise-filter-1208417506.webp?v=1764023683","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-accessory-ifi-audio-silentpower-isilencer-usb-noise-filter-1208417505.webp?v=1764023676","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-accessory-ifi-audio-silentpower-isilencer-usb-noise-filter-1208417504.webp?v=1764023679","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-accessory-ifi-audio-silentpower-isilencer-usb-noise-filter-1208417503.webp?v=1764023685"],"price":59,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:56.856Z"},"share_url":"https://firestarter.network/l/lst_xscsK1wT","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
