Best tube dampers that you have used


I currently have a Thor Audio monoblocks TP-150, 8  EL-34's Sovtek tubes for each amp.
Was wondering in anyone's experience will tube dampers improve the sound quality.
Am hesitant to proceed as I have read that  tube dampers can melt from the heat of the tubes and sometimes
cause smoke. Any thoughts would be appreciated.

If you're going to use a condom, make sure to roll them all the way to the base where the s/n is marked on them. You all know there is a s/n at the base of every condom right? I'm done now.
