I recently made a change in spk cable. My previous cable had spades on the amp end and bannana at the spk. The new cable I got has bannana's all the way around. I was a little concerned because I had also heard the sonic rule was #1 bare wire connection #2 spades #3 bannana. Now my observation my be skewed becaue the cables themselves were a significant sonic upgrade. The new cables have the factory terminated Z plugs. The terminations asthetically are beautiful and convenient. This bannana, unlike others, makes 100% surface contact because of it's design. It is gold plated berillium copper. I am very pleased with the sonics and the convenience of plug and play. No binding post wrench required, no worry about stripping the posts, and very very clean looking. I have not had experience with the WBT but I have read many comments that their topline bannana is also an excellent choice. The bannana is also convenient if you like to swap wires in and out. My wife says she also prefers the bannana! So there you have it :^)
