Do tube dampers really work?


Tube dampers are relatively cheap; but will they REALLY improve the sound of my Audible Illusions preamp?

Like others above, I also use the Herbie Hal-Os in my pre-amp-- very nice improvement, and like Jswhitlock, I found the Hal-Os able to change the sound as they were moved up or down the tube. Mine worked best about 1/2 way down. Cheers. Craig.
Another vote for Hal-o tube dampers. They worked for me in my preamp. Cheap too.
I am also in the Herbie continuim...nice little tweaks, bout' half way down as well..
I am using Shun Mook Valve Resonators, which are more than tube dampers, on the input and output tubes. I could not believe they work pretty well on my system (Berning amp) with more musical, lively and lush but detail... The Valve Resonators can adjust the sound you want. I will try them on my preamp later. Good luck.
