I just ordered sorbathane pucks for for my MK4 to try instead of the springs I've been using for 10 years. No matter what i did my woofers would jump no matter how softly I walked by my table. And this is with A Big Rock 19, floor jacks under the stand in the basement, reeplacing the sorbathane feet with brass spikes and puting BDR pucks under them. The only thing I haven't tried is an Bright Star Air Mass 19 for almost $600. A little out of my price range. But I heard going back to the pucks helps. We'll see...
