Reterminate with spades then use the Monster expanding banana plugs (Xterminators) which lock on to spades. Spades are waaaay preferable, and using this method you can have both spades and bananas.
Recommendations for banana plugs
I will be re-terminating a pair of speaker cables that have spades on them right now (two of which have broken)with banana plugs on both ends. I am unsure which brand would provide the most secure connection/best sound. Was considering the Eichmans or the Nordost type but have little to no experience with either. Does anyone have any suggestions? Thanks.
