iFi Audio Digital Enhancer iDefender USB C to A Ground Loop Device

Brand

The iDefender+ is a more specialised USB audio device, specifically designed totackle ground (or earth) loops that can cause real issues with some computer-basedsystems, typically resulting in an irritating buzz or hum from the speakers. When plugged into the source device’s USB socket, the iDefender+ detects whetherthere is a ground loop problem, caused by the presence of multiple earths that addnoise. It breaks the ground loop by ‘intelligently’ disconnecting the computer’searth; as well as eradicating audible ground-loop hum it lowers the system noisefloor, improving resolution and dynamic contrast.When used with a DAC that relies on USB power from a computer, rather thanpower from the mains or a built-in battery, the iDefender+ offers an additionalbenefit. If an external power supply is plugged into the USB-C socket on its side, itblocks power from the computer and instead feeds the DAC with power from theexternal supply; if a high-quality, low-noise power adapter such as iFi’s iPower isused, the performance of the USB DAC will be significantly improved.Like the iSilencer+, the iDefender+ upgrades the performance of the outgoingiDefender3.0 with the addition of low-ESR Tantalum capacitors for input and outputfiltering. It, too, is available in three versions to suit the connected equipment –USB-A to USB-A, USB-C to USB-A, and USB-C to USB-C. Again, the USB3.0 andUSB2.0 standards are supported and the connectors are gold plated.
