Power Cable will not fully insert. Help.

@roxy54  thanks. I brushed a microscopic amount of deoxit and it cut the distance in half so I’m leaving it. Nothing exploded (yet). 
 

thanks 😊

@twoleftears  I did indeed. I was unsuccessful in this but it’s probably due to my lack of experience. The first power cord took some effort but nothing like this. 
 

I love the effect these cords have and I have to say I agree with those who said power cords were as/nearly as big an improvement as speaker cable.  I didn’t and still don’t completely understand why or how, but love that they do. 

@lowrider57  I am hearing greater clarity, wider channel separation and lower bass than I was previously getting. 
 

Very happy. All my cables are AE except for power cables I have yet to replace. 

Thanks all.
