electrical short 1 channel. Cable spade at fault?


Excuse my electrical ignorance,but my YBA 201 is now out 1 channel after new cables.The spade connector to the amp was huge in diameter, 3/8ths inch vs 1/4 in.for the post,and even with it fully tightened there was still some motion possible in the cable-post interface.Also ,the spades were so long that there could have been some contact between the two.
Also,any ideas on what it should cost to fix this?
Thank you

In the long run, if you want to use these cables, the problem has to be addressed. I have on a few occasions taken cables to my garage and fired up my grinder and filed down ends. Then change to a buffing pad and smoothed out the filing.. Always good results. I can see you not wanting to do this, but I am very handy, built a few things from scratch, modded a few products and built a few cables. This is not an outrageous project. I have also cut off ends and replaced them many times also... Spades to Banana's etc... also, a fairly simple project... Litz is not fun to work with....
Thank you all for your good advice.
I can return the cables.
The real cost is repairing the amp.
I do consider the product defective, and I do hold the seller responsible.
