Wait a sec, sorry, I'm repeating the question to clarify and confirm, for anyone to answer. I hope I've made the meaning clear. At the moment I'm not talking about the cables that connect equipment together, like those terminated in a TRS, RCA, or BNC connector. Do you also replace any of the wire, cables, or traces inside your equipment (e.g. inside the box housing the amp)? If so, which ones, and with what?
