So $200 is the absolute upper limit on price we should pay on cables?
No, not for me. I'm more in the $300-$500 per cable, but I've bought pure sterling silver Musicable for stupid money, tried some higher-end Wire-World and Audioquest stuff, and Cardis. Small differences-- not better or worse.
Currently I'm running Morrow and I'm pretty happy with their approach, materials and careful build quality. I like quality connections, pure materials, and price really varies by length-- I prefer the shorter the better. I prefer no ferrous metals in the cable circuit, connectors, or panel connectors in the gear panels- replacing that stuff to all copper/brass/gold-plate makes a difference. Overall, I get way better bang by improving my room acoustics, vibrations, reflections, etc.
