I would not hesitate a moment to use a ferrule/screw tight termination. I feel this is a superior method to a soldered spade given the same metal make up of the spade. I hope mr. millercarbon has removed the brass connectors on his speakers, amps. And God forbid the brass rca plugs, speaker tabs, etc. There's no end to the ways an audiophile can lose sleep!
Seriously, for DIY this is a cleaner more conductive method than a blob of poorly applied solder on a large gauge conductor.
