iFi-Audio iPurifier3 USB
Ända från början har ett av iFi audios huvudmål varit att minska brus och försämring som kan uppstå när musik, kopierad till digitalt format, passerar genom en USB-ljudkedja. iPurifier3 innehåller allt företaget har uppnått i detta syfte och inkluderar dessutom en mängd nya funktioner.
Pure Obsession
In 2012, iFi invented the first USB power regenerator – iUSB Power. Soon afterwards it designed and manufactured its own professional USB audio cables – Mercury and Gemini. Then came the original iPurifier, followed in 2015 by iPurifier2 and now the iPurifier3.
Bigger in size but still only 69(l) x 19(w) x 20(h)mm, the iPurifier3 is packed with new components, not least of which is a further optimised version of its award-winning ANC® (Active Noise Cancellation) system adapted from military radar defence technology. Other additions include:
• OS-CON capacitors – these have a low Equivalent Series Resistance (ESR), excellent noise reduction capability, ideal frequency characteristics and a long life span.
• Tantalum capacitors – these polarised electrolytic capacitors have superior frequency and stability characteristics, giving them a super high volumetric efficiency.
• High-precision MELF resistors – metal electrode leadless face resistors have excellent accuracy, stability, reliability, and pulse load capability.
• New copper-alloy shielding – this excellent EMI shielding isolates devices and cables to block radio frequency electromagnetic radiation
