recommendations for tube dampers???

Top hats work well, but because you use a tube damper don't expect an improvement, and you may go backwards.

I had a guy grind me for an answer...will he like "X" tube damper?

First of all, in some positions, depending on the job of the tube, you may not hear a single difference in any way shape or form.

If it's the front end tube of a preamp or poweramp, you will hear a difference, but it depends on the tube in question. If the tube is already pretty tight, you may want to leave it. A smidge of microphony can be a good thing, and lead to a sense of "air" for right or wrong reasons.

There's nothing wrong with that. So the answer is nobody can tell you what to expect. We have more on that in our tube FAQ on our website

I tend to agree with Upscale on this. I use Top Hats and find them to be excellent on the principal tubes in my preamp, DACs and amps, but I note that along with better focus their effect can also be to rob a little of the euphonic sonic "glow" of some tubes which you may like. The ARC dampers are pretty cheap, I'd suggest them as a good place to start.

Upscale's comment about covers it. OTOH, for a couple of bucks, you can pick up three "O" rings for each tube at your local Home Depot. Get 'em slightly undersized and slip 'em on. Vary the number and position and listen. I've found them effective, sometimes not. As for Hats, Pearls and Sox, I've tried them all with varying or no success and, frankly, I don't think they're worth the expense. As for Herbie's, no experience with them, but they look interesting.
