I wouldnt recommend tinning the ends of the speaker wire..
This would color the sound possibly or change the conductivity of the cable...
Try using a good anti oxidant... Caig Pro Gold to
dip the end of the bare copper wire into and then insert it
into the hole in the binding post and tighten down the
post... This will prevent conductivity loss and promote better contact with the binding post. The benefit of non oxodized copper is longer lasting cleaner signal.
Good luck,
