So i'm looking at my shelf space and would really like to stack my record player on top of my receiver. I know it's not a good idea to just put it on there b/c vibration and heat, but have heard you can resolve those issues if you get 1 1/2" to 2" bouncy balls to stack the record player on. From what I've seen, people are just using blue tack to make sure the balls don't move. Anyone done this or know one way or the other if it is a good idea?
