I use the Neotech Sahara cables, they are rectangular OCC copper they sound superior to the round OCC but very expensive and the silver rectangular OCC is really crazy price, but the sound quality is exemplary.
I will say it again. Some people cannot hear differences between stuff like wiring, caps, etc. And because they can't hear differences they believe that noone else can. True, they get to save money.
if you tried the new tech silver and copper and they saw in a terrible that means your equipment is crap, OCC single crystal copper and silver are far superior to anything OFC on the market at any price that was proven over 50 years ago so if they sounded bad in your system you haven't got very good equipment because single crystal lets everything through good or bad so obviously what you're hearing is how bad your other equipment is.
