Bananna plugs


Is the use of bananna plugs for connecting loudspeakers to amp and receiver binding posts superior to just connecting the bare wire leads directly to the binding posts themselves? I picked up on this in a book I'm reading about audio and home theater systems. Do bananna plugs make for a more complete connection between the amp/receiver and the loudspeakers resulting in improved sound?

IMO the less you put between yourself and the music the better. NO connector is better than ANY connector.
Soldered is best but IMO Bananas runs a close second. Why? Unlike bare wire or spades, both of which make cross contact, bananas feed the signal in a direct line
Tweak1...Electrons can't negotiate corners? Perhaps the "tube sound" of amplifiers is due to the electrons being dizzy from their trip through the output transformer.
