Two Black Diamond Racing Shelf for the Source. Approximately 1.25 inches thick. One shelf is 18x17 inches and the other is 19x15 inches. They are both heavy, approximately 35 pounds each. Both have some light surface scratches. The 19x15 has a scratch that you can feel with your fingernail. Once placed under a component, both shelves are in very good condition and could be placed with bottom (label side) up with label obscured by component and would appear almost perfect. No longer manufactured by BDR. Especially good with Wadia CD players. Purchased from authorized BDR dealer. $450 each or $850 for pair.
