I have one of their shelves out in the garage.......It is an aluminum honeycomb with thin carbon fibre over it and I liked something else better under my amp a few years ago.....The shelf was 19" x 29" x .5" and bet it didn't weigh three pounds, extremely light and stiff......Taking bets it sounds different than the Linn components, but different isn't doesn't mean it sounds any better as only you can decide that.....Give it a try and report back as the price is right and assume you can change it back if you don't like it.....
