Speaker Cables

One of my favorites, which I still use on my office system was HD12D... something like that. Years ago, I think it was Stereophile or The Absolute Sound, just for fun, went to Home Depot and got a 12 gauge extension cord and threw it into the mix. It was actually really good. So, for my let's see... $5 or 6K system crammed in my office it is great. But for my main system with Sonus Faber Amati Traditional speakers and All Audio Research Reference stuff, it doesn't cut it.

For your main system, go up to 6 AWG then :-)
At that thickness, almost all copper wires will have negligible resistance.

Seriously, as I said, check the inductance and capacitance of the wire and buy accordingly :-)

Another vote here for Canare 4S11 cables.  Replaced a pair of shotgunned acoustic Zen Satori cables..  Very satisfied with them !

I find my Transparent Ultra cables significantly better in my main system. While I have not tried 6 AWG I feel I can trust the engineers at Transparent to have considered it.

@mastering92  to state cable synergy does not exist implies you can't hear a difference in cable performance.  IMHO that can only be caused by one of two things..  #1. having a system incapable of resolving the differences  #2. having a desperate need of a hearing aid.
