Have you made your own cables? and do you use 'em

Yes I have made Bees Wax coated CAT-6 speaker cables. They are still in my system and not going anywhere anytime soon. The Bees Wax coating takes DIY CAT 5-6 to a whole nother level. I've posted on this in detail before. I have used JPS Power AC cables for powercords in the past with good results on a Belles 400A amp and Morrison E.L.A.D. preamp, But DCCA power cords have retired me from the DIY power cord business for a while.

Made a few PC's using Belden 19364 14 ga. wire. Marinco or Wattgate ends. Still using them on power amp (Rega Maia 3), Rotel RCD-855 CDP and a vintage Sony VX5 Rec. Inexpense to make and sound just fine to my ears.

I've made dozens of different IC, speaker, power cords. Some my own brilliant design, some copies of internet site stuff.
Some silver, some plated, most copper. round wire, square wire, flat wire, solid, stranded etc. Some soldered, some crimped. All are in garbage. Presently using Pure Note Cerulean speaker, Ridge Street Audio Design IC on CD, old MIT T2 on surround analog inputs, Analysis Plus silver power oval on power amp. Has been much easier to get to sleep without multiple designs swirling about. Overall I prefer better Audio Note wire, expensive though, like most of the respected stuff out there. My very best wishes to you. Mike.
