Speaker terminal Loose

erik_squires   I try to open one Furutech end of the banana and broke one of the piece ! I think I would use BFA gold over brass crimping banana. Thank's.  I think Furutech are fragile with some  of their parts.

I found on my Furutech expanding bananas, if you remove the screw expansion pin, you can take a small file, and file down the area on the plug where the pin threads in, you can get more tightness due to the pin going in a bit further in, making for greater expansion on the banana plug. 

Works for me.

You are proving my point. You don't need to with WBTs.

;-)

Whatever you buy, something other than Furutech is my suggestion.

Soldered-on low mass BFA Style Banana Plugs for me, every time! I've been using them for more than 20 years and never had an issue. Never had one loosen. No problems, ever. I started with Nordost Z-plugs, but later changed to less expensive options that were functionally the same.

You can’t always blame the banana plug. Different manufacturers used slightly different binding posts over the years. I have gear where the same plug fits tightly in one component and loose in the other. Some plugs also fit deeper in some of my speakers. While close, there is no industry standard on the exact dimensions and there is nothing wrong with doing some minor fitting to get a tight connection.
I have tried locking plugs like the WBT.  The knockoffs I tried were made with extremely hard brass and I cracked one when I accidentally bumped it.   I am sure WBT uses a better alloy but it still has to be a relatively hard brass alloy.    I also became concerned with the amount of contact area with some of the expandable plugs.   If you out it in on oversized plug and expand it till it is tight........what is the actual amount of surface contact?  


I have had better luck with the BFA syle banana plugs.
