IFi Audio iDefender+ Type A > Type A — Ground Loop Reduction

Picking up unwanted noise in audio systems can be a common problem, especially when ground loops are present, causing hum, distortion or other noise. The iFi Audio iDefender+ is designed to intelligently disconnect the computer ground to eliminate these interference elements, thereby improving sound quality. With support for USB 3.0 SuperSpeed with gold-plated connectors, it ensures optimal signal transfer and maintains backward compatibility with USB 2.0. This compact module, measuring 50 x 20 x 9 mm and weighing just 6.6 g, is ideal for audiophiles looking for a simple and effective way to achieve clean sound.

Ground Loop Reduction and Lower Noise

When using the iDefender+ in a USB audio chain, ground loops are detected and subsequently interrupted. The result is reduced system noise, the elimination of audible hum, and improved dynamic contrast and resolution. This process contributes significantly to achieving a clear and undistorted listening experience.

USB DAC Power Options

For USB DAC users, the iDefender+ offers the option to block power from the computer and replace it with clean external power via the USB-C port on the side. By using a quality low-noise adapter such as the iFi iPower X or iPower Elite, you can significantly improve the performance of the USB DAC. This approach eliminates the influence of computer noise and ensures a stable power supply.

Improved Circuitry and Components

The iDefender+ features optimized circuitry, including low ESR tantalum capacitors, which improve input and output filtration by up to 10x compared to previous models. Thanks to these components, the device is able to effectively "break" ground loops and ensure consistent performance. Gold-plated USB 3.0 connectors not only improve signal transmission, but also extend the life of the device.
