Thank you for your clean‐cut explanation. I'll get micro iUSB3.0 first. I can have a good night's sleep tonight.

Hi @iFi audio I really like iGalvanic3.0. I want to upgrade my set up again. Which is better to buy first iUSB3.0 or Gemini3.0 cable ? I can afford only one of those. Someday I'll get another. Gemini3.0 is new product. So I think Gemini is more effective, Its better to buy first. My set up ...

I understand what glassmonkey and technobear said. I thought Normal PC cannot recognize which port is for data and for power. It must work like single head usb cable. But It was wrong. Gemini cable controls it, its not PC's task. So if two ports are available, I can use gemini cable. Thank you...

Thank you for your reply. It brings me more questions. In this case Gemini work like single cable? If so, I think it doesn't work fully functionally. Mercury might be better choice. I wonder Gemini is good choice only for users they have micro/nano iUSB3.0 ?

Can I use gemini 3.0 cable like this picture ? I wonder if I can use it without micro/nano iUSB3.0. https://www.phileweb.com/review/article/image.php?id=2803&row=5
