Sayonara mechanical hum.

Mains electricity, crucial to your audio systems, can often be disrupted by various interferences, distorting the AC waveform, and reducing audio quality. ‘DC on the mains’ is a common problem, particularly with amplifiers.

Although household outlets are intended to deliver pure AC power, a range of your home appliances—from lighting controls to home appliances power supplies—create ‘asymmetrical loads’, resulting in DC voltage on the AC supply.

When a small amount of DC voltage from the mains reaches the transformer, it can cause ‘saturation’, leading the transformer to produce a significant and persistent humming sound. You can hear it when you bring your ear close to or next to the chassis.

The DC Blocker+ is a smart device that, when you place it at the IEC (the rear power inlet), prevents DC from getting into the amplifier, thus eliminating transformer hum.

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

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.

The iPurifier 3 is a USB gadget that reclocks, regenerates and has a rebalance tech, it incorporates a active noise cancelation technology that works impressively, a revised and upgraded version of the last itineration of their iPurifier 2 I also own, as always the unbox experience of the package from iFi products is very specia
