Spades or bananas connectors?

You could never tell the difference in a series of blind tests.

Don't kid yourself into thinking you could.

My experiences tell me that as long as there is that big, fat, hunk of metal called a binding post in the circuit it doesn't matter too much what the termination is. Realizing that removing the binding posts is not feasible for most people, I vote for getting the termination that works best for a given situation. I am assuming that which ever terminal connector is chosen is of good quality.

For those who can do this, try bringing the wire from the speaker out and connect directly to the speaker cable. You can use the binding posts to pinch the wires together. It is very surprising how much is lost going through those posts.

That's why Vandersteen speakers don't have binding posts.

Dynaudio is difficult for spade connectors,bananna is the best way to go with Dyns..

Audiofeil - I might never tell the difference but purists prefere crimped (not soldered) spades. I installed AQ spades by crimping and then soldering with 4% silver solder heating wire first to avoid expansion (loosing oxygen free connection). Audioquest does not solder their ICs to avoid additional metal (they weld). I know, I know - I won't be able to tell in blind test but I don't see reason not to - doesn't cost. Each small thing like that might not bring noticable change but it adds up - like peeling almost clear layers from pink sunglasses. Each peel is not noticable but eventually glasses will become clear.
