At the amp end, alot has to do what will the amp binding post accept. Most all will accept a banana connector/bare wire. Not all will accept a spade. On nearly every one of my amps/int. amps I've changed out the binding posts. I like Superior Electric. (Have really gone up in price lately but worth it, IMO.) They will accept bare wire (Up to 14ga. wire, spades and bananas.) On the spk. end, I like bare wire that is tinned only at the end of the wire. But the contact is made w/the pure copper. This way no stray wires. This method can be used on the amp end as well if you have a hole in the binding post. I perfer bare wire followed by spades. But a banana conector sould work in all applications but IMO is not the best connection b/c on some binding posts they don't go in very far.
