Not trying to be contentious but isn’t the question of DH Cones vs Herbie’s Tenderfeet also a question about the relative merits of vibration draining vs vibration damping/isolation?
I’ve read at least one "expert" recommendation to use both: a hard cone (brass in this particular article) under a component (point facing down) to drain vibration into a wood plinth and a softer elastomeric footer between the wood plinth and the equipment rack shelf to provide vibration damping/isolation.
I’m not arguing for or against anything here, just wanted to provide a slightly different context for considering the OP’s question.
