What is it use for and the benefits?

Many cables combine power and data into a single cable, causing crosstalk between power and data. iFi Gemini USB separates the signal ground from power ground and shields the signal and power connections from each other.

In regular USB cable often only one shield is used; aluminum metalized foil is commonly used instead of copper shield. iFi Gemini USB uses dual heavy shielding, use of both aluminum foil and copper braid shields, each work for different frequency range to produce the best shielding ever. It also employes custom-designed metal connectors (not just for looks) to provide impeccable shielding from end-to-end.

Often RF filtering is non-existent, even if filters are fitted, working over too narrow a range, too few are fitted and common RFI filtering is placed at the ends of the cables, leaving the whole length of the cable to act as effective antennae. iFi Gemini USB fitted multiple filters all with a different effective range. Further the middle filter may be adjusted (moved along the length), to “detune” the antennae formed by the cable.

The signal connections use 2 gauge heavier OFHC continuous cast copper, with the geometry adjusted to keep the correct impedance. Very stringent requirements for impedance tolerance, much narrower than the USB 2.0 standard allows.

For grounds and power lines a 5 gauge heavier pure copper connections than common is employed. Keeping cable resistances low, this allows for excellent power delivery to the USB audio device from the iUSB Power. The iFi Gemini Dual-Headed USB Cable cuts power supply resistance in the USB link threefold compared to “textbook spec” cable.

yes i saw this post before but I still don't really understand it. is too technical for me. In a nut shell better signal leading to better clarity is it?

Generally yes. This cable addresses not just the quality of signal but also RF interference rejection so as a cable itself is quite a complete solution.
