Double spade connectors?

I owe a ML No. 383 which, unfortunately, has only one pair of binding posts to drive my ProAc 3.8s. I am using Van den Hul's The Revelation Hybrid (= appr. 10mm). I have tried bi-wiring with this cable and doing so improves the sound dramatically. However, the Levinson binding posts are too small to give place to two spades (WBT spade connectors). Does anybody know whether "double" spades are available? I mean spade connectors that have a double entry for two large single lead speaker cables?
