I saw a guy in an electrical shop in Cork spending >€100 on 3 IEC power cables with sheilded cables for his sensitive audio equipment.
I asked him did he also intend to sheild the entire supply cable back to the xformer and perhaps from there back to the powerstation?
.... people sometimes make me wonder if they should be allowed to wire anything! Never mind tinning the cables for that professional look. Also, you'd want to be careful when suggesting "tinning" anything in Cork, it could be misinterpreted as "thinning" with warm and sparky results!
