Tightening binding posts problem

If they are loosening up on you try a littel teflon tape on the threads. This won't affect the transferance as long as the spade is up against the base of the connector. Teflon tape is available at any hardware store and won't damage your threads.

use pliers or get the lug nut to tie them with wrench.
i also used to have the same problem with Creek amp where I couldn't tie binding posts strong and once they shout-out the output stage so i believe such remodeling or installing different high-quality binding posts is worth.

I've had great results using an Audioquest Speaker Binding Post Wrench. $9.95 from most retailers.
Happy listening.....Erik

I use an appropriately sized socket (without the wrench) to hand tighten.

In addition, where the speaker cables exit the spade, I will point the cables at about the 4 o'clock position (instead of straight down at the 6 o'clock position). As I hand tighten using the socket, I'll using the other hand to turn the spades/cables toward the 6 o'clock position simultaneously.

This method seems to work quite well at providing a very snug connection between spade and binding post.

-IMO

I had the same problem with binding posts that were plastic sleeve over metal lug with a burr that seats in the plastic. Over time, changing cables and tightening stripped the plastic over the metal and I had to replace them with all metal binding posts. Michael Percy has a good variety.
