The swirl on my bubinga is intense and multi shaded, and it makes the knick *really* hard to see unless you are doing a close inspection. The depression is not really visible, you can only feel the dimple by running your finger over it.
Quite honestly the thing that bugs me most about my Salk speakers is how shiny they are. I can see light reflecting off my drivers, *through* the grille and I always thinks its a dust spot on the grille or something. The corners of the plinths make nice points of light as well, and I always think the dog knicked the corner or my wife or something. Always turns out to be just shiny. I have 7 Salk speakers, 3 of them have knicks, the black corner of my SongCenter, a tiny one on the front of a rear SongTower, and the one on the side of the SongTower today.
Edit: It doesn't bug me that its shiny per se, but that I perceive the shiny as some sort of unbeknownst damage. I have little heart rushes at least a few times a week.
