Mr. khiak
I'm not giving up on you. Let's do it step by step:
Look at this: https://imgur.com/a/OimyIhJ
It shows you the screen when you enter the "imgur" site. Look at the top (header) left side. There is a green area with a cloud icon and text: New post. Click it.
Than a new window is opened: https://imgur.com/a/wVEylZH
Drag the picture you want to upload into to the dotted area with the giraff picture. After the upload finish, you will get again a screen like this: https://imgur.com/a/OimyIhJ
At the right side there is a black background with a URL address and a button that says "copy". Push the copy or mark the URL address and when marked, use the Ctrl+C to copy.
Than go to the post entry of Audiogon, at the place you want to have the URL placed and use the Ctrl+V to paste the URL address in your post.
I need to see what you did with your DIY endings and the banana plug you used to answer your question. I still stay with my old recommendation to use the Nakamichi plugs:
They do excellent contact, they are very easy to work with, they are firm and can get up to 8 AWG wire.
