Key Features Explained
SuperSpeed USB 3.0
‘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.
Breaking earth loops
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.
Active Noise Cancellation
The iDefender+ removes electrical noise (including EMI/RFI) at source using iFi's Active Noise Cancellation II circuit. This process enables bit-perfect transfer of audio data to the DAC.
Plug and Purify
The iDefender3.0 plugs into your computer USB port and auto-detects if there is
more than one earth and will ‘intelligently’ disconnect the computer earth for a
cleaner sound. It eliminates ground loops that keep the DAC from functioning
properly and compromise the transparency of the restitution.
Block and Replace
On top of saving your computer from the unwanted earth, if your DAC is USB
powered, iDefender3.0 can block the computer’s power supply and replace it by an
external power supply. Injecting clean power will ensure you get the maximum out
of your USB audio. It significantly reduces the system noise floor and makes for
better dynamic contrast, warmth and resolution.
How do I use?
iDefender+
When plugged into your chosen USB port, the iDefender+puts a stop to ground loop hum andlowers the noise floor resulting in audibly better resolution and dynamics.
SilentPower Reviews
★★★★★"With the iPower2 the noise disappeared completely with the volume at maximum! That silence is what I expected. I heard the music better! The ZEN Air phono with the addition of the iPower2 goes from being a surprising device for the price, to being surprising for its performance"
Guido Ruiz Barría, Surcos de Jazz
★★★★★The iPower X fever-level transformers introduced this time provide the purest DC power supply equipment. Power supply, iPower X is an AC / DC transformer with extremely low noise. Its small volume is filled with a lot of ifi Audio’s exclusive technologies and fever materials
My HiEND Magazine
★★★★★I believe it is a great everyday carry accessory not only for sensitive IEM/Headphone users but also for beefy headphone amplifier owners who would like to hook up their IEMs to these amps and crank the volume as far as they can. The iEMatch 4.4mm gets the highest recommendation I can give to an audio accessory.

★★★★★"This article was born in my head a long time ago, mainly due to repeated questions from time to time, whether I had contact with filtering devices like iSilencer, Jitterbug etc. But since I run my humble blog, I’ve probably got used to most people to a few maxims, which I am guided in total not only in the field of audio equipment, but generally in life"
