No one actually knows how to lculate what speaker cable they need

My two cents on spades ending for speaker cables:

They tend to get lose after some time. A continuous maintenance of fastening the binding posts is required. Banana plugs are way better.

For those who try to implement a thick cable (4 gauge or thicker), the spades that can fit the cable are too large to fit the binding posts. You may lose on that contact between the spade and the binding post some of what you gain from a thicker cable.

For me, if an amp or speaker is not fitted for a banana plug, I'll would avoid it!

We will see when the first guys here will return after giving it a shot and share with us their impression. A little patient and we are there.

I've seen what happened with some friends who listened, didn't doubted me for a minute, and ended up very happy.

I'm assuming that the spade comments are for my benefit? If so, thanks.

I can get the cable unterminated and use a cable reducer to drop the cable down to 4awg. Once it's 4awg it'll fit in a banana plug. Or I can use a distribution block to join 0awg and 4awg and run a very short length of 4awg direct to the terminal on both ends. Would either of those approaches work?
