This is one of those things that has annoyed me for so long, that I’m putting it up. I have despised, no, I have friggin loathed the quality of 1/8″ (3.5mm) cables. Cables are pretty easy; just clip, strip and solder away, right? Right. If you grew up cursed with the junk that rat shack carries, you know my pain. So, if you hate those crappy cables as much as I do, go check out this lovely little write up on making quality interconnects. (Now if I could just find a 2.5mm connector like that switchcraft 3.5mm to fix this spare apple power supply)
