The iDefender+ removes USB ground loops, reduces noise, and improves your DAC or streamer with cleaner power. Read more.
The SilentPower iDefender+ is the perfect solution for audiophiles looking to get the best out of their digital audio chain. This clever USB accessory ensures a clean and stable connection between your streamer, DAC, laptop, or computer. By isolating ground loops between USB devices, the iDefender+ effectively eliminates unwanted noise and restores true musical detail.
When multiple powered USB devices are connected, even small differences in ground voltage can create loops. Unlike analog circuits, where this often results in a hum, in digital audio it leads to added noise, reduced resolution, and a loss of dynamics. The iDefender+ solves this issue instantly, delivering a clear and refined listening experience.
If you use a USB-powered DAC, the iDefender+ also protects against noisy power lines from your PC. Thanks to its second USB-C port, you can connect an external, high-quality power supply such as the SilentPower iPower X. This provides clean power to your DAC and results in improved sound quality, better dynamics, and a more natural audio reproduction.
