I too am interested in more information on these HD cables.
Here are my initial thoughts:
I like what xyz says has been his method for comparing;
I am concerned however that there is no mention of this brand anywhere else on any audiophile forum or review I can find;
The cable is relatively inexpensive so might be worth a tryout if a little more info were forthcoming;
I too am interested in knowing what is the list of cables against which xyz's group compared
I'm currently using a Marigo Apparition unbalanced. I am about to swap in a kubala sosna emotin balanced, to compare.
I have tried blue jeans, Kimber, audioquest and a couple others I can't presently remember. The Marigo is better in my rig, to my ears, for my preference than all previous by a wide margin. Better imaging, more clarity, sweeter top end, tighter bass, fuller soudning, etc etc.
If these HD proves better than the likes of Marigo and kubala sosna, they should be able to sell a lot of cables here. But I'm unready to lay out $400 without more information.
