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.

Wilson Sabrina, Pass XA30.8.
hope this helps but do call Wilson Audio to confirm

I measured 5/32” spades on my speaker cables attached to Sasha DAW Speakers and coincidentally Pass Labs Amps.  Doesn’t look like 1/4” Spades would work- might be tight.
