Speakon NL4FX - a step backwards?

   I've only ever used the NL4FX until tonight, where I made up a cable with NL4FC ends. 

My impression of the NL4FCs: Wires seem to go in easier, however Neutrik could have at least identified the terminal poles like the Fxs. Trying to decipher which plastic tit on the connector corresponds with the crappy image on the plastic bag is of little help. I think I prefer the FXs, which have the pole numbers and polarity marked on the connector.

Regarding the solder vs crimp vs fidelity issue: I would wager money in a double blind listening tests, nobody could hear the difference; and in my opinion, solder is a more reliable, robust, permanent, low resistance connection. Except I don't think the higher heat involved for solders with silver content would be good for the plastic insulation of the speakon connectors.

Skin effect doesn't become a significant consideration until you start trying to pass radio frequencies down the cable.
