Hello Norh user,
I have a pair of black Marble7.  It sound pretty good, but I have been having trouble finding a compatible stand for it.  i have tried many things, but the marble weird weigh distribution on stand seems like an accident waiting to happen.  
I live in bay area, California, with American cherry wood floor.  I don't want to have these marble fall and make hole in the beautiful wood floor.  Therefore, I keep taking it out of the box, put it up for a few weeks, and pack it back up again.    
I am would like to know what do you guys use as speaker stand for your marble.
Thanks
