I have recently purchased an EquaRack system. It doesn't use shelves, but a series of isolated aluminium mounts fixed to a heavy-duty steel frame. It had a great review and has been compared with the Grand Prix. It has fully lived up to my expectations. I am using Shunyata Python power cables and the lack of shelves makes it easy to dress the cables and keep them free of the floor, other kit and the rack. The sound is great and the system is flexible enough to allow me to add another level at a later stage.
