So you can hear differences using the damping rings. You just have to be careful to not overdo it, because the damping rings reduce the tube's ability to get rid of heat. Heat will shorten its life. That is why dusty tubes don't last as long.
IME on a small signal tube I've never heard one degrade the sound. They can be helpful if the preamp is in the same room as the speakers, since the more still the tube is the less microphonic it will be as well.
