What's the biggest spade you can buy?

I have this problem all the time, especially at the speaker end with speakers from Europe. It's enough to make you want to switch to bananas. Cable manufacturers should consider moving to larger spades as the standard offering.

I'm sure other MF owners will have some advice, in the meantime, wow, those are huge terminals. The largest spades I'm aware off is Monster's 10mm, but they only work with Monster's locking pin system.

Besides other MF owners, I'd try talking to a MF dealer or the company itself for advice.

just a bit off the topic, but bare wire is the best!

I used to have this unit and the banana connection fit very tight & sounded great. That is the best route for this unit.

Alpha Core solid silver spades may work.
