I have now read this whole thread and I am intrigued by the power cord. I recently purchased the Hiijiri Takumi RCA cable after doing an extensive A-B-C comparison with Inakustic, Hiijiri, and the Tchernov. What a shootout it was.
I also noticed that many of the people on this thread are from the Helix Dueland DIY thread. I had 6 of those power cords made for me. I am sensing even though the H-D power cords are good, the Hiijiri are just on another level in SQ and price.
It has been a couple of months of dormancy but I would love to hear if everyone owning the Hiijiri power cords are still saying these are end game.
