Thanks todd & dhal. I wouldn't totally discount bare wire but am unsure how to remove the banana plugs. I did receive a response from HiDiamond but my Italian is till so there's a slight communication issue. This is essentially the advice I got,
'Please send photo. If the problem is the final plug , your possible buy other banana and change. The bananas are normally forgotten on the wire and not solder.'
