iFi Audio iDefender+ USB Audio Ground Loop Elimited & SilentPower iPower 2 Low Noise DC Power Supply

iFi's iDefender+ provides a simple solution for those grappling with noisy audio caused by unwanted ground loops in their audio chain. Combining it with the iPower2 5V, which effectively cancels out incoming EMI and RFI noise, ensures you never feel powerless against noise and graininess again. The iPower2 features enhanced components and thicker wiring for improved output/input noise suppression, and it comes with five differently-sized adapters, including a reverse polarity option for professional audio products. Break the ground loop with iDefender+ to eliminate audible hum, lower the system noise floor, and enhance resolution and dynamic contrast. Additionally, when using the iDefender+ with a USB-powered DAC, it not only breaks the ground loop intelligently but also allows for the injection of 5 volts of clean power via a separate USB-C port, significantly improving the DAC's performance, especially when paired with iFi's iPower X. The iDefender+ ensures optimal signal transfer with its high-quality gold-plated connectors, making it an effective solution for overcoming hum, buzz, and distortion in your audio setup.
