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.
 

2. iFi Audio AC iPurifier

The multi-talented AC iPurifier from iFi Audio cleans the power grid of disturbances and makes your music sound clearer. Whether you are an analog lover, a digital junkie, or both, the AC iPurifier cleans and protects your system. It is designed for anyone whose audio system is affected by interference or distortion due to dirty power. The AC iPurifier frees your system from electromagnetic (EMI) and radio frequency (RFI) disturbances, ensuring a clean, clear sound in no time.

The AC iPurifier utilizes Active Noise Cancellation technology developed by iFi Audio and inspired by military technology. It actively eliminates far more noise across the entire frequency range than products with passive noise suppression. The AC iPurifier features built-in grounding and polarity detection. The two LED lights indicate whether the plug is correctly inserted in terms of polarity and whether grounding is present.

iFi Audio's intelligent grounding system ensures that the AC iPurifier does not introduce a ground loop when it is not needed. Use the 4.4 mm grounding socket with the confidence that the AC iPurifier, through its smart design, keeps your system free from ground loops. No ground loops mean no annoying hum or buzz, just interference-free clear music in your ears.

Thanks to the built-in surge protection, the AC iPurifier shuts down when it detects a short circuit or surge. Your devices remain safe and intact at all times. You can plug the AC iPurifier directly into a wall outlet or use a power strip. The AC iPurifier is equipped with a Schuko plug and can operate with 100 to 240 volts. The more AC iPurifiers you use, the cleaner your power will be.
 

3. iFi Audio iDefender+ USB C – USB A

Is the sound of your audio system affected by noise, hissing, buzzing, or humming? The iDefender+ from iFi Audio is designed for anyone dealing with disturbances in the audio signal due to unwanted ground loops in the audio chain. Using multiple plugs in your audio setup means separate grounding points. These multiple grounding points create a ground loop problem, leading to unwanted noise.

Here comes the solution: When the iDefender+ is plugged into the USB port of the source device, it detects whether a ground loop issue exists. The iDefender+ interrupts the ground loop by intelligently isolating the grounding of the computer. It not only eliminates the audible hum of the ground loop but also reduces the system's background noise and enhances the sound resolution and dynamic contrast.

Are you using the iDefender+ with a DAC powered via USB from the computer rather than from the mains or an internal battery? Good news: the iDefender+ offers an additional advantage. When an external power supply is plugged into the USB-C port on the side of the iDefender+, it blocks power from the computer and instead provides the DAC with clean power from the external supply. When using a high-quality, low-noise power supply like the iPower X or iPower Elite from iFi Audio, the audio performance of the USB DAC is significantly improved.

Thanks to the iDefender+, you can enjoy a noticeably enhanced sound quality, as all disturbing noises such as humming, hissing, buzzing, and noise are eliminated. Additionally, the iDefender+ also improves the stability of the USB signal, helping the DAC or amplifier reproduce the signal more cleanly and accurately. It is compact and lightweight, making it easy to integrate into any audio system.
