I use a layer of black felt to separate my synth cabinets. I don't
connect the cabinets together horizontally. But I use 4 metal pins
(leftovers from some IKEA furniture) between the cabinets, vertically,
so that the top cabinets stay aligned with their bottom.
A lot of my studio furniture is DIY and I've used black felt as a
separator between speakers, monitor bridges, and various synth stands.
Felt doesn't seem to decay or leave any residue at all. I also tried
using rubber feet but those always seem to get either gooey, or
brittle, or leave a visible mark behind.
