    Our refurbished products are in excellent or nearly-new condition, typically returned within our 30 day return period.

Each purchase usually includes original accessories, with some replaced by equivalent alternative that offer the same functionality.

    Is your audio still taking a beating from buzz and hum? iFi’s iDefender+ is for those battling with noisy audio due to unwanted ground loops in their audio chain.

    Using multiple plugs within your audio chain means separate earth/ground points. These multiple earth or ground points cause a ground loop problem. This creates an unwanted chain of noise, buzz and distortion. Struggle no more - iFi’s iDefender+ provides the simple, effective solution you need.

    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.

    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.

    SuperSpeed
    ‘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.
