I use very heavy brass dampers from Vintage Tube Services on the four 6SN7s in my Rouge 99 preamp. I have switched them in and out and used them with a variety of 6SN7 types.
I can report a tremendous sonic benefit. Bass is dramatic both in depth and definition. The soundstage is defined. With the dampers, highs are pleasant, not harsh.
I won't use tubes without them.
I do have the Herbie Halo dampers on the small signal tubes in the Zeus power amp. I do not notice much of a difference there, however.
