Not sure how much help this will be but here goes.
I have a Monoprice amp stand that I place the shelf piece from an old Cotter B-2 turntable stand on top of. Herbie tenderfeet on top of the shelf with my DAC resting on the feet. On top of the DAC are 2 PPT Omega mats with more tenderfeet on top of the mats with the RS2-T finishing the pile.
