Your passport to pure, uncompromising USB sound
The USB iPurifier Pro from iFi Audio is much more than just an accessory: it is a complete, compact audiophile solution designed to eliminate interference on any USB connection and deliver an exceptionally clear sound experience. Combining the heritage of three legendary technologies, the iGalvanic3.0, iSilencer and iDefender, this USB purifier acts as a true noise shield, ensuring a clean and stable connection between your digital source (computer, streamer, network player) and your DAC or audio interface. Compact yet powerful, it fits easily into any digital audio system to reveal all the finesse, dynamics and micro-details of your music, while ensuring ultra-fast, lossless data transfer.
Galvanic isolation: Stopping parasitic currents at the source
The USB iPurifier Pro uses state-of-the-art galvanic isolation to electrically decouple the input and output parts of the USB signal. This separation eliminates parasitic currents and time jitter that can affect the accuracy and musicality of your audio streams. By removing these interferences, the device ensures cleaner and more faithful transmission of the digital signal, for a denser, more stable sound reproduction, free from unwanted noise.
Active noise reduction, USB free of EMI/RFI
At the heart of the USB iPurifier Pro is active noise reduction technology similar to that found in noise-cancelling headphones: it detects electromagnetic interference (EMI/RFI) and generates an opposite signal to cancel it out. The result is a significantly reduced noise floor, freeing the soundstage from interference and allowing your DAC to operate in optimal conditions, revealing every musical nuance with unprecedented clarity.To complete its arsenal, the USB iPurifier Pro incorporates IsoGround technology, which intelligently manages ground connections in complex systems, eliminating ground loops and stabilising the signal. It also offers data transfer speeds of up to 10 Gb/s, ensuring that signal purification never comes at the expense of speed or compatibility with high-resolution audio formats. From pure signal to fast bass, no detail is left to chance.
