looking for exotic affordable wire suppliers

I've been playing around with various wire lately, building my own interconnects and power cords, and I'm quite satisfied with the results. I've sold many higher end cables over the last few years and I can honestly say that I'm not missing them (well, maybe the 6Sons Audio Golden Eagle pc). I have a nice stash of Oyaide and IeGO AC plugs as well as some some excellent rhodium over silver RCA plugs (can't recall the manufacturer--out of business) but I would like to find some alternative wire options. Everyone has copper or silver or gold +/- variations but I'd like to find some palladium or rhodium (plated) wire, perhaps even platinum if prices aren't too crazy (I think the BMI Shark used platinum wires and that was a vivid though bass shy cable). Does anyone know a supplier for such wire? The only ones I've found are pure solid core wire and these are way too expensive. Thanks for your advice in advance.
