There's no good reason not to use bare wire (or bare wire tinned with solder) unless the gauge is too large to fit through the hole in the speaker binding posts.
I recently bought Morrow speakers cables with "nude" terminations at the speaker end, although I chose spades at the amp end for reasons of convenience only.
Nick Gowan of True Sound advised me to use tinned bare-wire terminations on Audio Note speaker cabling for the best sound.
