Don't look for any flames from me, I'm a believer in cable differences. Heck if I ever hit the lotto I'll even spend huge dollars trying out the audio jewelry types offered. In the meantime, til those numbers hit, I've experimented with all kinds of cables from cryo'd Cat-6 single strand to severely discounted PS Audio cabling (currently in use).
Sounds as if you hit on cables that really work for your system, and you know that is a joy!
I am waiting for a new preamp to be handbuilt and shipped, and breaking in a pair of exceptionally good interconnects for the preamp, the "Decware Silver Referrence" interconnects. Really enjoying the relaxing sound. . . !
