no clue where the community stands on this, but i think the cheap ones are just terrible, they really harm the signal. I recently removed the stock set (Dayton's) from the external x-overs on my speakers, and a whole world of sound opened up.
I think the general idea is that the connective parts of our systems should do no harm to the signal...up until a certain price point though, they do.
If i run across a situation where I can't hardwire, i try and use Eichmann's Cablepods. A lot of folks use the Edison posts, which seem to be the best of the old school 'chunk of brass' designs. cryo-parts.com sells these. Both pairs i mention are $50 a set.
in the end its up to you and how your use your system. IF you need big spades and easily torqued binding posts, then so be it. i'd get curious though and see how removing them works, then work backwards so they function the way you like but don't kill that magic that removing them probably brought out.
