Do tube dampers really work?


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

Hee....

What was the reading with the same tubes prior to fitting them with the Halo dampers? That would make this a meaningful comparison..
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..
