Here is the first shelf. Home Depot 1/4 inch steel brackets lag bolted to
studs behind drywall. Two layers of 1/2 inch birch plywood with a 2 inch layer
of Y20 dense foam. Under the Thorens TD160 MK 1 is a Brite Star Iso-Rock platform.
This shelf eliminated the foot fall issues I was having, allowing the Thorens to play
undisturbed by vibes that previously, were constantly working it's suspension. Sonic improvements were
apparent and substantial.
