Suggestions for DAC isolation?


My DACs transformer hums/buzzes slightly and I would like to control some of the associated vibration. The DAC is relatively light weight (not in sound). Contacted the manufacturer who said it's normal.

It currently resides on a 3" thick maple slab with 2 VPI bricks on top. Large Audio Points brass cones under maple slab. Thinking about Still Points, Finite Elemente, Black Diamond type units between the maple and DAC.

Maybe something like the Finite Elemente Resonator/The Sound of Silence on top.

1. Has anyone had similar problems?
2. Any suggestions for controlling vibration under DAC?
3. Mass loading or vibration dissipation better on top?

Thanks for any insights you can offer.

I've only heard of one manufacturer who openly stated that one channel of their DAC will hum and that it couldn't be heard once music was played. That was Valab.
Now that they have the power transformer in a separate case, their is no noise at any volume setting with no music playing. Toroids are notorious for their nasty sounds and interference unless properly shielded. Heed all the advice given above until something works.
