http://www.richersounds.co.uk/index....tl.php&p=43711 I have got these banana plugs. I can't figure out how to use them. Well, actually it is almost impossible to use them the way I figure... There is a screw which is very small, and the hole which I assume for the cable to be inserted is very thin, my cables don't fit in there. There is this second hole above the screw hole, I don't know what that hole is for. I thought banana plugs were produced to fit almost all types of speaker cable. I didn't notice that "4mm", and I guess that means they are OK for cable upto 4mm thick? I bought 10 pairs of them and no returns, will be a pity if they come out useless.. Any idea if I can use them with my cables?
