The OP asked us for 'cost no object' recommendations, so here goes:
Most of us don't have the money even to rent these cables so we won't have heard them but I did 10 minutes googling.
Siltech Triple Crown power cable costs £55,000 for 2m. Price of a very luxury car.
Anyone heard it? (not that you can listen to a power cable). Please read my previous posts on power cables before reaching for your wallet.
By a strange coincidence Siltech price their Triple Crown speaker cable, 2m stereo, at £55,000. Clearly the manufacturing costs of these different cables are not the same. So the £55,000 price has been plucked out of the air for the mugs to latch onto with both hands.
Siltech Triple Crown interconnect, 1m XLR, is a relatively affordable £25,880/pair.
By the way Miller, did you get to hear any of these?
I disclose that I have used Siltech interconnects for 25 years. Much cheaper then and certainly not the flagships (no funny metal boxes). I like them and have seen no reason subsequently to experiment or change.
