@richardhk. Apologies for taking months to reply! I do not have notifications on and did not realize you had asked me a question.
I have been in the AV industry for years and have contacts in this industry. One of my friends and colleagues works directly for AQ so I learned this information first hand. AQ has developed proprietary geometries for the positive, negative and ground cables in their new power cords. They do not disclose what the varying geometries are but they have learned that particular designs work better for different poles. This is part of the magic that apparently helps these cables to sound so good! This is ground breaking if you ask me and I am excited to try one in my system. I will hopefully be acquiring my first one in a couple of months and will
of course report back my personal findings!
