If you want the warmest cable, then use the Furutech gold-plated XLR plugs with some low grade solid-core copper wire like below:

Keep it all gold-plated / copper. This would be a very warm sounding cable I can imagine. The gold-plated is already warm sounding and the low grade tinned copper wire will really roll off the high frequencies. This would not normally be a cable I build, but it would still sound good because of the solid-core wiring. It would just lack higher frequency resolution. If you want even warmer with less highs, use a larger low grade 18awg solid core hookup wire. The larger awg solid-core wire just cannot reproduce the higher frequencies.
From there, it goes up in resolution. That Neotech OCC solid-core copper wire is hugely better than the cheap stuff and carries much more resolution, but it will still not be bright/harsh like silver. 20awg is the sweet spot for best bass and best high frequency resolution. VH Audio has their "UniCrystal Cu AirLock" hookup wire that is better than the Neotech, but it's only available in 18awg and 21awg.
Silver wire/components will be faster with more attack and perceived resolution, but it's very easy to go over the line and the sound becomes artificial and non-engaging. Silver can have a tendency to push the upper mids and can sound thin in the bass. Some systems that are really warm / laid back can benefit with a little bit of silver.
In my mind, rhodium plated is the end game. It gives much better high frequency extension than silver and it doesn't push the upper mids. It's also very natural sounding (not like silver) and has incredible bass. The downside is that Furutech rhodium can be really expensive and it takes a long time to burn in (300-400 hours). The burn in process can be very painful and hard to listen to (many people have given up because they just can't listen to the hard edge of the burn in).
