What size Spade for Wilson Audio Speakers

Old thread, but I have a similar question.

Do I need 1/4" or 5/16" speaker cable spades for Wilson WP6? 

Also do I need 1/4" or 5/16" spades for Pass Labs XA60.5 amps?

I've researched this and haven't found an answer. Wanted to get some cables this weekend but guess I will call Wilson next week.

Can I just be safe and order the 5/16" spades on both ends since 1/16" of an inch really shouldn't matter?

Thanks.

Thank you for your help @tonywinga and @audphile1 .

Seems Wilson and Pass are the way to go.

I will go with 5/16.

Thanks again.

Just following up here, 5/16 inch spades worked just fine with WP6’s
