Defend Your System from Hum and Buzz
Using multiple plugs in a system can cause a ground loop problem, which generates hideous, unwanted noise. The iFi iDefender+ solves this problem by plugging into the source device’s USB socket, detecting whether there is a ground loop problem, and then disconnecting the computer’s ground signal. This lowers the system noise floor plus improves audio resolution and dynamic contrast. When using the iDefender+ with a digital-to-analog converter (DAC) that relies on USB-C power from a computer, the iDefender+ offers an additional benefit: it blocks power from the computer. Instead, it feeds the DAC with “clean” power from the external USB-C supply. As you’d expect, Sweetwater home audiophiles treasure having such a simple and effective to “beat the buzz” in their home audio system.
