Gemini 3.0
Key Features
Exceptional design
Our iFi FINAL USB connectors provide impeccable end-to-end RF shielding, being machined entirely from solid, aircraft-grade aluminium. Plus gold-plated connections make for years of steadfast service.
The Power of RF3
Most standard USB cables do not address RF issues and are fitted with filters that work over too narrow a range and are only fitted at the ends of the cables, leaving the length of the cable to act as an antennae.
SuperSpeed
USB3.0’s ultra-speed bandwidth of 5.0Gbps offers an incredibly wide bandwidth, 10x that of USB2.0’s 480Mbps.
Two heads are better than one.
The power cable is heavier gauge than often found in standard USB cables. And signal and ground have their own respective geometry for optimal conductivity. There are dual-headed designs and then there is the Gemini3.0 dual headed design. Nothing comes close.
The golden touch
Most USB cables use moulded plastic covered connections that do not shield the high frequencies present in the USB data link. Noise radiates out. Very few make their own connectors and rely on off-the-shelf components. These often lack durability.
Our FINAL USB connectors provide impeccable end-to-end RF shielding. They are machined entirely from solid, aircraft-grade aluminium. Plus their gold-plated connections make for years of steadfast service.
Degrees of separation
The Gemini3.0 cable carries the audio signal and power in two separate cables. This separates the delicate USB data signal from the USB power. No interference and sound quality remains unaffected.
How do I use?
Gemini 3
Connect the USB 'A' Audio connector to a USB port on the computer. Connect the USB 'A' power connector to a USB port on your computer. Finally, connect the USB 'B' connector to a the input of the USB DAC/Sound card/Interface card etc.
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.

★★★★★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

Frequently Asked Questions
All cables can only degrade.
So with cables, you get degradation for impedance mismatch and signal degradation.
The closer the cable adheres to the impedance spec (90 Ohm) the less impedance mismatch derived degradation.
Equally, the lower the various losses in the cable (related to the amount of copper, plating, isolation, and geometry), the lower signal attenuation, and thus the signal level degradation.
If either degradation becomes too large the USB signal is cut or unreliable, before obvious problems are noted (cut out, no connection) sound quality can still be affected.
However, the regenerate/reclock/rebalance technology that we implement in our products can largely revert the degraded signal.
Good cables simply cause less degradation to start with.
USB was never designed to carry high-quality audio hence in effect laying interconnects and PCs side by side the USB cable was not a “problem”.
Our flagship USB cable, Gemini, separates audio & power (the equivalent of separate interconnects and PCs) whilst the RF silencers on both of these cables are urban dwellers for example, where there are numerous radio stations emitting strong signals that would benefit from. Lastly, the 90 ohms is a big deal as this is USB standards and anything that differs from this may cause some issues.
The Gemini functions as follows;
The audio symbol only carries data & related
- – (Negative) and + (Positive)
Power symbol only carries power & related
- 5V and Ground
The Mercury is standard having all 4 contained in the one USB cable.
As there are 2 types of connectors for the Gemini/Merury3.0, here are the EAN numbers so you can inform the retailer for the correct one.
Mercury Cable 3.0 (USB2.0 ‘B’ connector) - 0.7m (5081313081752)
Mercury Cable 3.0 (USB2.0 ‘B’ connector) – 1.5m (5081313081769)
Gemini Cable 3.0 (USB3.0 ‘B’ connector) – 0.7m (5081313081776)
Gemini Cable 3.0 (USB3.0 ‘B’ connector) – 1.5m (5081313081783)
The Gemini functions as follows:
Audio symbol only carries data & related
- Pins: – and +
Power symbol only carries power & related

The Mercury is standard having all 4 contained in the one USB cable.
24AWG and 28AWG.
So-called ‘audiophile USB cables’ are often of questionable construction and are neither certified to USB standards nor do they conform to the USB specifications relevant.
In this case, they often do not work various combinations due to them straying away from the industry standard.
Any cable certified according to and conforming correctly to USB 2.0 standards will work, however.
