Solid core OFC vs stranded OCC copper

I used Cardas for my speakers and amp , but it is harder to work with than other choices .  24awg from RCA inputs to 9.5awg to speaker binding post outputs .

Neotech makes OCC up to 12 awg both solid and stranded ,

so why would you want solid OFC ?

Who  manufactures the speakers and  What size and type wire is being used now ,  have you or are you going to upgrade the crossovers ?

On the Thiel forum there is a lot of conversation about internal wiring ,  I myself rewired using Cardas 17.5awg for the tweeter , midrange and using 15.5awg for the woofer , where the original wiring was 18awg solid  .  I have also upgraded the components on the crossovers .

It's very cool that that the manufacture makes an upgrade kit for the crossovers , but new drivers too !

Whichever way you go from my experience I'd stay away from silver plating over copper wiring , either use pure copper or pure silver  .
