How do I connect my speaker cables to this Coda Amp

I changed the binding posts on my upper set to posts w/o the safety cover. Pop the top and get out your soldering iron and Bob's your uncle.

Otherwise you could try an adapter on the spade that is a banana as Erik suggests.

Dill is right, but so far I can't figure out how to get that plastic cover off the post.

I will take zlone's advice and try again with perfect alignment of the spades .

If I could get them to line up I know the nuts would screw down tight. 

In the mean time I have a call in to Doug Dale at Coda to see what he says.

I can't thank you all enough for responding. 

If this is like my Pass Labs XA25 amp that has Furutech binding posts with the clear cover, try the following.  If you are looking from the front over the rear of the amp, there is a slit at the top of the clear part that the spades slide into and then you tighten.  It took me quite a while to figure this out after I first bought a spade to banana converter thing from transparent cables.  See if yours is like that.  I would take a pic but everything is packed up for a move.  Good luck!

I just looked up your amp.  Those appear to be the same as the binding posts I have so it may be worth a try. I have the standard size spades on Nordost cables (Purple Flare)

WBT terminals that Coda uses are some of the best!
