‘SuperSpeed’ USB 3.0 has a more exhaustive wiring specification which allows for a greater amount of audio transfer while still being backwards compatible. The units incorporate high-quality gold-plated connectors for optimal signal transfer.

Beat the buzz
Break the loop
When plugged into the source device’s USB socket, the iDefender+ detects whether there is a ground loop problem.It breaks the ground loop by ‘intelligently’ disconnecting the computer’s earth and, as well as eradicating audible ground-loop hum, it lowers the system noise floor, improving resolution and dynamic contrast.
Using a USB DAC?
Are you using the iDefender+ with a DAC that relies on USB power from a computer rather than power from the mains or a built-in battery?Good news. The iDefender+ offers an additional benefit. If an external power supply is plugged into the USB-C socket on its side, it blocks power from the computer and instead feeds the DAC with ‘clean’ power from the external supply.If a high-quality, low-noise power adapter such as iFi’s iPower X is used, the performance of the USB DAC will be significantly improved.
New and improved.
We’ve upgraded the circuitry; low-ESR tantalum capacitors have been added for improved input and output filtering. Filtering capacitance has been increased 10-fold.The iDefender+ now comes in 3 versions and includes the newer USB-C connector.- USB-A to USB-A
- USB-C to USB-A
- USB-C to USB-C

Kills USB power noise by ‘breaking’ the earth/ground loops in the correct way. It significantly reduces the system noise floor and makes for better dynamic contrast, warmth and resolution. |

Inject 5 volts of clean power via the ‘separate’ USB-C port. This disconnects the USB power from the PC and replaces it with clean external power. For ultra-low noise, use our 5-volt iPower Elite or iPOWER X. To ‘break’ the earth/ground on USB-powered DACs, adding a separate 5 volt supply is necessary . This is not required for DACs with an internally-powered USB section. |
