Impressive thread drift! 
Back on topic…
I agree with Richard that the pictured cables both look like NACA5. See this thread for more details on how to confirm.
BTW, what are some thoughts on A4 vs A5 sound differences?
I haven’t done any formal comparisons, but have run both 4M of A4 and ~6.5M of A5 on my Chrome Bumper 62/HiCap/140 system.
Obviously, it’s not a fair comparison due to the length differences. Again, I wasn’t really trying to do more than a casual comparison. However, both sounded excellent to me on that system. Nothing stood out as broken when I switched from the longer A5 to the shorter A4.
(On the other hand, I have noticed clearly audible differences while doing length only comparisons of A5 (only) on my main 252/250DR system, FWIW. It’s been discussed before, but I may start a new thread on that topic)
