Ladies underwear, eh? Haven't tried that one yet.
Latest tweak: My wife's grandmother had my wife's baby shoes bronzed back when my wife was just a little girl (apparently, this wasn't uncommon then -- not sure how common it is now). Anyway, they're both bronzed and then each placed on a heavy bronze pedestal/bookend. They're quite heavy and have a soft felt covering on the bottom. So I decided to place them on the barren expanse of black steel that is the top of my SCD-C333ES because (A) I think it's cute to see my wife's shoes from when she was a baby (and that big, empty black metal top was looking sorta plain), and (B) they very effectively dampen the top of the case, totally
eliminating the little resonance that I could hear when I tapped my fingers on the top (and even the sides) of the 333.
Haven't done any A/B with/without the shoes on top of the 333.
