Binding Post?

Jason, you are thinking backward.  Your source puts ot a signal, call it 100%, good as it gets.  Every component in the signal path degrades it.  You want to minimize the degradation.  No passive component ever adds anything, it takes away.

@carlsbad : then get rid of the binding posts and solder the speaker wire directly to the internal connections.

Okay, funny story with this subject.  It's all true though.   Years ago, my wife, now ex, had three cats.  They would run around behind my speakers and disconnect the banana plugs.  I had satellites and two subwoofers on each side, so there were a lot of banana jacks and plugs.  I got tired of missing some of my music every time I turned it on, so I ended up getting locking banana plugs.  Pricey at 30$ a pop in 1985 money but it cured the problem of cats yanking the jacks out.  So, in a roundabout, kinda sorta way, expensive banana jacks made all the difference in my system. 

I used them up until a month ago when I switched the subwoofers and sub amplifiers over to 5/16's crimped and soldered terminal lugs and #12 AWG dual quad speaker cables.
