Oddly enough, that pic is demonstrating the one scenario where I opt for spades rather than banana plugs. If the bore on the speaker is deep or open ended, a Deltron can go all the way in. But if shallow, then the last third doesn’t insert. That’s fine with a lightish cable but I’ve had bent Deltrons in the past (recent past) with any cable heavier than A5. The further off the ground the connectors are, the more cable weight they support.
Some speakers and amps have banana terminals that will even only accept half a Deltron. So it’s cheaper short spring leaf banana plugs or spades.
