Product Review

The iFi Mercury USB cable takes the standard USB transmission protocol and re-writes it for high-end audio. Crucially, the special geometry adheres to the 90 ohm impedance specification better than even the USB 2.0 standard. Resistance is 3x lower than textbook. The FINAL USB machined connectors are proprietary for exceptional shielding and rigidity. The atypical RF3 filter design is user-adjustable. With all these technological breakthroughs, one audition and there is no going back.
