Not sure it is accurate to say they “ are vastly outperforming the competition”. Competition is a great big universe of brands and none of us have heard them all. Also, Hijiri is marked by a certain beauty of flow, tone and purity that will appeal to many, but perhaps others will want more of this or that other sonic attribute. The whole subjective thing comes into play. I will say they must be heard to find out if they “do it” for you like others have experienced.
Cable making is every bit an art also. Two cooks may be given the very same ingredients and asked to prepare the same dish. Both can taste very different. Cable building with like materials is the same. The Hijiri designer is skilled with the ingredients he uses. This is also a piece of the Hijiri “magic” as it should be. Can’t read about this in specs etc….
My speaker cables appear to be high purity, solid core copper. The connectors are very high quality, but I don’t know if they are made internally. The Nagomi power cord is very flexible suggesting stranded conductors.
There are many online reviews to be found on his offerings.
