Where to place tube dampers on preamp tubes?

I agree with Audphile 1.

As far as the black damping ring supplied by ARC, this is what ARC says,

"The single black damping ring should be level and located 1 1/8" (1.25" or 2.8 cm) above the bottom of the glass portion of the tube as measured from pin end of the tube to the center of the ring".

"Take care when installing each tube in its socket so that you don't push the damping ring from its proper position".

If you accept that no tube damper eliminates resonance, then like almost all other hifi tweaks, you're just putting a "fixed tone control" in your system, and maybe a transient clarifier. Hence a further variable is the placement of the damper on the tube. Also the tension of the damper. Its mass, etc., etc.

If you're going to use these things to tune the sound of your system, you might be reducing elements that obscure information, but more likely you are making a compensatory adjustment for some other trait in the component or elsewhere. Therefore, just work the remaining variables and keep it up until it's better than it was before or your patience or interest run out.

So what are you trying to say? Do you have tube gear? Do use use tube dampers on at least the driver tubes?
In your posts you mention alot about tube equipment.
Do you consider hi-quality caps and resistors as tweaks? They will effect the sonics of an audio system.
