from w/w CARPET to WOOD floors

You don't say how your system currently sounds. Are you having a problem, or is this just something you're thinking about? In most cases, people prefer carpet over hard wood floors. Also, berber is probably a bit more reflective than traditional carpet. I feel its somewhere in between.

Well, if you cook the pasta al dante, of course its going to fall off. And you're probably using spaghetti, or something else really smooth. If this was for dinner, that's one thing. But for audio, you need to get a rough pasta like rigatoni, and over cook it. That way you have more surface area to work with from the ridges in the noodles and over cooking it means more drying time, which allows for better bonding.
