I believe Jadem6 is guiding you straight. The results you will likely obtain in this case should be stellar. Nice bass articulation, some welcomed warmth and smoothness in the mids and highs with good extension at either end.
A couple things I would add though: many people on the bleeding edge of the metallurgy scene are now beginning to embrace tungsten in preference to gold. It is said to be even more dimensional with even more bloom and even smoother - in fact rather liquid sounding from the lower mids on up...all without sonic downside. But, I myself don't yet know how to source it or how much it costs.
Also, and although it's possibly a bit of a moot point really, but (just in case you don't know it already) in your OP you talk about OCC wire moving better than non-OCC wire. OCC wire has far fewer crystal boundaries, which of course they say is what makes for better group delay (in the conductor) and lower resistance. But, keep in mind (at least for future reference), that under a microscope, every time you bend the strands you introduce micro-fissures - no big deal per se with OFC - you have all those crystal boundaries per inch impeding the flow anyway. But, OCC wire is a different animal - almost no boundaries to start with at all. Introducing micro-fissures all along the length of this wire creates impedance (raises resistance) and introduces smearing. This is why you often don't (or shouldn't, at least) see OCC wire tightly braided into aggressive geometries. At that point about all you can really expect to have is an OCC design with just about equivalent performance with the same wire made from OFC - only more expensive...! I would bet the same holds true for either copper or silver (and bending probably doesn't do gold too many favors, either...but, I suspect gold is at least pliant enough to not incur as many micro-fissures from bending as copper or silver). Regards and good luck.
