The type of DIN speaker plug pictured in the Ebay listing is an inferior type.
It's practically impossible to lock the wires beneath the screws slightly conical heads, they squeeze the strands away
and isolation between the wires and any stray strands is almost
non-existent.
It doesn't take much twisting of the wires/cable to losen and/or short the plug/speaker/amplifier with a potential expensive repair as a result.
Sorry, but in my opinion this type is a no-go for our B&O.
I use a different kind, usually grey, where the strands goes
into a barrel-type screw-mount and the screw goes into the barrel from the side.
This type comes in both male and female and
bought in bulk the price is apprx 2 euros each if I remember correctly.
This slightly higher cost is money well spent and shouldn't knock over any B&O owner.
