Cheap Ass Cables & Voultar's SNES Jr. RGB mod vs. competitors - eviltoast

One of my favorite mods to do is restoring RGB and S-Video capabilities to the NTSC SNES Jr. (which is a cost-reduced version of the “one-chip” SNES) using voultar’s mod.

What I want to know is this: why can I use a cheap-ass friction-welded Aliexpress SNES multiout RGB NTSC SCART cable (EXAMPLE ONLY, I DID NOT BUY FROM THIS PERSON) to connect my voultar mod SNES Jr. to the OSSC, and I have a PERFECT PICTURE on my HDTV, when, alternatively, I use the console5 mod with the same cable and OSSC and I have sync issues (sometimes a distorted signal, sometimes “No compatible signal” black screen from my HDTV)?

Voultar uses a better video amp than most of his competitors, mainly because with the THS7374 you can disable the LPF, while most competitors use the THS7314/7316 video amp with the LPF permanently enabled. But this should not impact sync, should it?

Someone explain why I can use stupidly cheap cables on voultars SNES RGB mod but not other’s mods.
