This is exactly the feedback I was looking for. Very much appreciated.
When folks like grannyring, lak, wig, & lalitk all report fairly similar results, and some of those users also having used Audio Envy and Zavfino, you can have a better idea of how even the Hijiri Performance line is also a value. Let me explain. I mentioned a $1k power cord in my intro. Audio Envy's $179 and $279 power cords were both better by a fairly large margin than the said $1k PC. So if these posters are saying that Hijiri is much better than Audio Envy and Zavfino, at the price that grannyring mentioned for the Hijiri Nagomi power cord above ($1,350), it is still a solid value in that it handily beats the AE and Zavfino power cords. And understand that grannyring and maybe others in this thread have spent a lot of time building cables and so have a larger world view of wire and how it works, you can then understand that when the Hijiri are recommended by them, that they must be pretty good. I have some experience with trying different power cords, but certainly not to the extent that grannyring, lalitk, wig, and others do. So their experience and insight with Hijiri can be highly useful for many who read this thread, certainly for myself.
