Re-terminate speaker cables

You can get a tighter connection with two screws rather than on one spade.
WBT locking bananas are cheap. No need for Cardas solder or cold weld.
Unless you can't work a screwdriver.

Screwdrivers? You don't work them, you drink them.

@OP,
Sorry to hear AQ didn't respond.
Alasdair is usually pretty good at getting back.

In any case, AQ terminals can be user replaced, just get the ends you want and use a jewelers screwdriver.
In your case, you could simply stack two spades together.
You can PM me, I am having work done on my cables, as well.

It is easy to do yourself but it is a shame to hear a story like that it is easy money for them to re terminate the wire and make sure the customer is happy.

Use a screwdriver. LOL I can't.. I don't know how, BUT I got a 50 ton press that says they will be one with the music and never come loose in your lifetime EVER.. :-) Do you know you can get 10 TONS of pressure with hammer strikes, one handed.. NEVER move again.. A speedo cable arbors is what I use now for cold welds.. Easy if you know what it is and what your doing.. It is the BEST way to join anything electrical, Compound crimps too.. Screws come loose. I've retighten my mains 10 times in 20 years at least.. JUST to clean the contact..
