Rather depends on what you want. B&O still sell the original cables with 2 pin plugs at one end and sockets at the other. Maplins in the UK sell both 2 pin DIN plugs and sockets so that you can choose which wire to use. If you go for the B&O variety, get the extension cable, not the speaker wire as the wire on the extension has both the plugs and the sockets - the wire has plugs at one end and bare wire at the other which is for Red Line speakers.
