Wow - a lot of vitriol with respect to Lovan racks. I admit, they are not the greatest, but at least the Sovereign model can be improved if you take certain steps.
First, replace the shelves with something custom made - the MDF shelves are garbage, and the glass shelf sounds steely (and is expensive to boot). I recommend either acrylic or corian. Alternatively, maple or other hard wood of at least one inch thickness could be used as shelf material. Next, use some constrained layer damping material between the shelf and the frame (as opposed to those circular felt/sticky pads). The frame should be filled with a combination of lead shot and sand. Finally, if you are adventurous, put a set of pro MIBs under the four feet.
Admittedly, the above changes raise the price of the racks to almost double the list price, but it works pretty well, and is still much cheaper than any of the "real" high end racks.
