Hopefully easy question: speaker cable spade size

I don’t know your specific amp but if it were I, I would go with the 8mm ones. Here is why: I bought expensive speaker cables with spades on both ends. The manufacturer used small spades because that is what they themselves manufacture. All my amps use the larger posts and the spades do not fit. When I called the manufacturer, I was told to put one side of the spade into the hole in the post and tighten. That is what I have done and although it sounds fine, it bothers me.

If if you use the larger spades and the post is small, you can always squeeze the tips of the spade a bit for a more snug fit. Just my 2 cents.

As Levinson is still in business, I would try to email/phone them.

I thought about it but not sure they want to answer tech questions about stuff they sold 25 years ago.
