I have one of these audio racks having upgraded from an older Sony unit, with sand filled legs and MDF shelves. The Usher rack makes a better sonic difference to the music, and it is also a class peice of furniture.

I use mine for my turntable, SACD player, pre and power amps.

Actaully made for Usher by Agora Acoustics in Korea, and they make some sensational audio isolation equipment.

Well made, easy to assemble and SOLID. Comes with adjustable floor spikes, so you can level the rack. Money well spent. The last audio rack I will be buying.
