Accessoiries like heavy valve caps and Lefreque plates in essence add mass to an instrument, which do alter the instrument in some ways.
The difference between playing with these mostly have an effect on the player as they might ease slotting, articulation and centering. I believe that you can tell a difference listening to Dave’s recordings, but the difference is so subtle that you need the side-by-side comparison to tell the difference.
I don’t know if I would use one on a Prestige to be honest as it would make an already heavy horn even more heavy. If you bought yours new it should have come with a second set of gold-plated bottom caps for valves 1-2-3 that are of a different weight than the ones already installed.
