I've made several sets of speaker cables using crimp on connectors from Analysis Plus. I put spades on the speaker end because I don't want the weight of the cables pulling down on banana plugs. Plus spades are more secure if you occasionally move your speakers around seeking the perfect spot or just to vacuum underneath. I put bananas on the amp end because the connectors are usually an inch or two above shelf with minimal strain on the plug. Also, the connectors on the rear of some amps can be quite cluttered making bananas the easy choice. I use a ratcheting crimper which produces a proper secure crimp every time.
