iFi audio nano iGalvanic
Love your computer audio? But plagued by buzz, hum and jitter?

The iGalvanic3.0 can help. It will lift your computer audio to the next level.

It’s down to earth

If computer audio is your thing, then you know about digital signals and how annoying interference can be.

Listening on a Mac? These aren’t earthed so produce a natural buzz and hum (I can hear mine now!)

Using a laptop? Their earth adds distortion due to multiple cables.

No mean feat

Never fear, the iGalvanic3.0 is here. Galvanic isolation on USB3.0.

It is for any computer system. Plug into any USB port via your DAC. Put simply, it ‘creates’ a new, interference free signal.

No more noise, no more jitter. (And not an easy thing to do on USB3.0!)

One-stop USB solution

The iGalvanic3.0 is the one-stop USB audio enhancement solution for every computer audio lover.

It uses audio-grade galvanic isolation, REclock/REgenerate/REBalance2 and a clean USB power supply.

Ground breaking

Our iGalvanic3.0 breaks ground loops, avoids noise-coupling in applications that require hi-speed USB transfers and dramatically improves sonic performance.

Perfect for audiophiles seeking maximum sound quality from their USB digital audio system.

This is the world’s 1st audiophile-grade galvanic isolation on USB2.0 and USB3.0 on an audiophile grade device.

Electrical circuits are separated to eliminate stray elements – a signal can pass but nothing else.

Built-in super noise converter.

A super low noise audiophile grade USB power with Panasonic OsCons.

All computer audio systems are different. This product is dedicated for computer audio use and incorporates Groundlink.

A flick of the switch optimises isolation in systems where there is no, one or multiple grounds (earths) which cause hum and/or buzz.

A highly advanced isolation technology, without any added conversion, processing, timing uncertainties or delays. It is native, and Bit-Perfect with minimal latency.

REclock2, REgenerate2, REbalance2® – cleaner, clearer music. The 2nd generation of this technology creates an all new signal, eliminates computer jitter and removes noise contamination to restore a ‘balanced’ signal.

Blown away

I use an Apple Mac laptop and I avidly listen to music through my DAC into this. But when I visited a friend I noticed that their music seemed much clearer and smoother than mine. When I got home, I realised mine had a low grade hum to it – something I never really noticed before but now seemed glaringly obvious and really annoying!!! It also seemed less smooth I guess. So my friend suggested iFi to me, we had a good chat and he talked me through what he thought were my issues and options.

It came down to the iGalvanic3.0 being the one to best suit me, and suit me it did. Once I had set everything up and hit play, my mind was blown. The clarity and sleekness of the sound is astonishing. I don’t know how I went so long listening to my music the old way, I’m definitely never turning back! I am looking forward to my friends coming over just so I can show off my set-up. Will be purchasing the Groundhog+ to further help my issue with the missing earth.

Galvanic Isolation

Galvanic isolation is a design technique that separates electrical circuits to eliminate stray currents that contain noise. Signals can pass between galvanically isolated circuits, but stray currents, such as differences in ground potential or currents induced by AC power, do not pass. This means little or no noise interference to the audio signal from stray currents.
