Walpurgis,
They sound good even with the spades and I was in such a hurry to get the new binding posts in and the speakers playing again, I just left them.
As an aside though, when I set the speakers up for the first time my 12 guage cable would not fit in the clamps of the original binding posts and I was forced to use some old thin cable I had used on a AV setup (maybe 16 guage), that sounds as good as my 12 guage (to my ears), perhaps my ears aren’t what I think they are?
In any case, my 12 guage drops down to those 2 thin wires pictured, I probably should not of bothered with heavy cable.
