OP: would you please explain your rationale for opting for a selecting vintage WE wire for IC materials? It obviously works for you CD player, so nothing appears wrong with it. Just curious.
As for the hum and noise, try grounding the WE IC at the preamp’s ground post. Check for local ground loops in or near your turntable.
