With an unlimited budget, why don't you ask someone to custom design them for you?
Or even better, a custom cable loom?
I would look at Argento Audio, they make everything themselves, the connectors are made with the same silver as the conductors, and attached by compression, no solder used. "Organic Audio" are the same cables but made with copper instead of silver, built to the same standards.

Bocchino also makes complete cables, not only connectors, you could ask for a full custom cable looom, made from your materials of choice for both connector and cable, again attached without solder, so asking for a full cable loom may not be a bad idea if money is not a concern.

This one is also worth mentioning, presumably the next level of cable building, no solder or compression to attach the cable and connector are needed, because the entire cable is one piece of silver (!!!), this is, in my opinion, extremely interesting:

If I had enough money to burn it, I would also ask for sockets made to the same standards to fit all my equipment (Schuko, IEC, RCA, XLR, etc) to avoid any bottleneck and enjoy the full potential of such a magnificent cable loom, go big or go home!
