★★★★★

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

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

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.
