They enjoy the sweet hell of their creation and there’s no one gonna tell them any different. Enjoy!
Well, it is true that the particular wire I am using is notoriously brittle. Doing your own reliability and quality engineering is part of DIY. Brother let me tell you about the steam powered rocket ship I'm trying to build ... :D
Truth is when it comes to IC's I gave up on them. I have a box full of WW Eclipse 6, and compared ot them, the pure silver, balanced and shielded is either good enough for me or I'm not bothering. I have about 4 pairs of IC's I've built, and unfortunately all the other's are far longer, hence the switch.
When it comes to speaker cables, I realized after doing some single blind testing that the cables I liked were actually making things worse. I was trading a lot of mid-treble energy for imaging.
As for the power cable, I don't know if it sounds exactly like a commercial cable, because so far I really can't hear a significant difference from it to 16 gauge plain black. I'm not made of cash, so instead of others suggesting I buy off the shelf cables it would be nice if others built these cables instead. :)
Of course, it is about time for my hearing to deteriorate as well, so we can make that argument, in which case I think what's important is that I not buy stuff I can't hear a benefit from.
