i have a d.i.y. rack with 4 x 20mm thick Panzerholz B25 shelves, & a double-thick (40mm) top-shelf.
top-shelf supports nearly 350lbs (Vibraplane 2210 + Micro Seiki SX5000 t/t with mods, motor & HS80 flywheel).
i've not done comparisons / do not know what sonic character Panzerholz imparts, but this material seems very inert & strong (shelves do not sag unlike some "high-end" racks i've owned).
