Well, if you can't get it to work, th two guys above gave you a good solution.
Spade lug connector to Marantz amp
How do I connect speaker cable spades to a marantz N30 amp? Best Buy says I need banana plugs but the Marantz manual says speakers spades work. They show a diagram but it seems a plastic piece is in the way. Does the plastic piece have to be removed? Thanks
I will also visit Best Buy today to review.
