Thanks for the recommendations, very helpful. I think I actually may just DIY the cables at this rate. Looked at the prices and saw that the actual cables for even $200-600 cables are being sold from the manufacturer for about $0.93/ft.
Is there a good place to read about the kinds of cables/wire available, and the best connectors/terminators to pair them with? Is there a good thread I can read for the equipment I need to make a proper cable? I have a lot of shop equipment on-hand, so if it's standard stuff, I probably have it all already. The Oyaide and Furutek bulk wire suggestions look very attractive.
The main thing I'm struggling with is that I'm going to have a cv transformer located 20ft or so away, so I need to figure out the best way to manage that distance in between. I was thinking of having a good quality splitter run directly from the transformer, then use 1.5-2m cables to connect from the splitter to the amp, D/A, etc. One thing I'm not sure about is if I need a fantastic cable for that 15-20 feet of distance between transformer and splitter, and if all the cables need to be the same, like if I had to stick with the Furutech or Oyaide throughout. Qty2 4.5m cables and qty1 7m cable would probably run close to $700 for the wires alone for the Oyaide, and that doesn't count the connectors.
Ofc, that's still far, far cheaper than buying everything premade, which would easily be in the thousands.
