...a rare appearance from Elizabeth - wow nice to hear that you're still around...
Lock; you should try the marble on Vibrapods thing. I recall that someone else did this & had good results. Try to work out with the downstairs neighbor so you can put on some "test music" & then listen from their unit below yours. Explain that you are trying to accomodate your music to their privacy; you'd think that they would then be quite cooperative. Then try some various approaches to find out what works best, & to determine how loud you can crank it before they experience any problems downstairs.
