Anyway, I can live with it now that it is under control. Frankly, unless the problem reappears, I'd prefer not going through the hassle of a return. But I might give them a call just as an FYI.
It would be interesting to know, however, if other LFM-1 owners notice any changes / improvements by weighting the top of the cabinet.
