I've got speaker set up on a long surface along with amp and tt - all well spread out - surface is a purpose made unit that runs the width of the room with records underneath. I don't have room for floor standing speaker stands so I was wondering whether there might be an isolation solution that I could put under the speakers on the unit. I've seen wooden and granite ones being sold but if anyone had a view on these and whether they are worth bothering with, I'd be grateful. thanks.
