I think expectations are always part of the problem along with defining what somewhat might be stating when saying something "sounds" better. I read this before purchasing it, and I take all this with a grain of salt when the price tag isn't in the stratosphere.
I think this is a good definition of what to expect from the damper, noting that the rest of the chain will also play into it.
"I slowly started to realize that although the soundstage wasn't any 'bigger'-seeming, it was effectively deeper, because I could now 'focus my ears', so to speak, more precisely all the way to the backmost reaches and still maintain the sense of clarity and definition."
"In the big picture, I'd characterize the changes wought by the addition of the fluid damper as being on the order of about 10% or so (quite good), but in the particular areas upon which it has its greatest effects, I'd say they were more like 50%, which I think is excellent. No, I didn't get 'more' bass or dynamics, but I got less of what the presence of such information in the grooves can do to the more fragile parts of the sonic tapestry. In my estimation, what I'm hearing now with the damper is more faithful to the music mastered into the vinyl than what I was extracting previously, mostly through the reduction (if not the outright elimination) of some of the more pernicious effects engendered by the process of attempting to trace microscopic squiggles with a flexibly mounted needle attached to the end of a freely swinging arm."
