carver m 500t amp wiring problem

the binding posts seem to only hold pins[not bananas]or bare wire.biwiring is difficult as the wire gets crimped and is not snug.what can be done?
Monster cable makes connectors that fit over the thick bear wire and have a thin braded gold plated wire that easily fits inside the binding post. Their available at Circut City for $ 19.99 for 4
thanks weiserb.i don't know why vendor of the biwires didn't say anything about that when i explained the problem
