1. iFi Audio iDefender+ USB A – USB A
Is the sound of your audio system affected by noise, hiss, hum or buzz? iFi Audio's iDefender+ is for anyone struggling with audio signal interference due to unwanted ground loops in the audio chain. Using multiple plugs in your audio chain means separate grounding points. These multiple grounding points cause a ground loop problem. This creates unwanted noise. Here comes the solution: when the iDefender+ is plugged into the USB socket of the source device, it detects if there is a ground loop problem.
The iDefender+ breaks the ground loop by intelligently disconnecting the computer's ground. It not only eliminates the audible hum of the ground loop, but also lowers the system's noise floor and improves sonic resolution and dynamic contrast. Are you using the iDefender+ with a DAC that is powered via USB from the computer rather than from the mains or a built-in battery? Good news. The iDefender+ offers an added benefit: when an external power supply is plugged into the USB-C socket on the side of the iDefender+, it blocks the power from the computer and supplies the DAC with clean power from the external power supply instead.
When a high-quality, low-noise power supply such as iPower X or iPower Elite from iFi Audio is used, the sonic performance of the USB DAC is significantly improved. Thanks to the iDefender+, you can enjoy significantly improved sound quality as all distracting noises such as hum, hiss, buzz and hiss are removed. In addition, the iDefender+ also improves the stability of the USB signal, which helps the DAC or amplifier reproduce the signal more cleanly and accurately. It is compact and lightweight and can easily be used in any audio system.
