What size Spade for Wilson Audio Speakers

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.    

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.

Yup good synergy 

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