Lovan audio racks....and other racks.....

Lovan racks are not too bad, considering that they are modular and flexible. They are just "out of fad" now. I had used them in my system before, but they are now around the house doing other duties, because I got an unbelievable deal on these Solid Tech racks.

Good: Modular, stackable, cones under each module, cheap on the used market.
Bad: flimsy MDF shelf

If you are to use Lovan racks, here are a few things you should do:
1/ use glue gun and fill the gaps around each of the legs;
2/ fill each leg with sand about 1/2 full to start with;
3/ shop around your local granite kitchen countertop stores for cutout pieces. It pays to shop around, as you will be quoted anywhere from $20 to $200/piece.
4/ go to parts-express.com and purchase sheets of vibration dampening sheets, sandwich it between the granite (top) and the MDF shelf (bottom).
5/ use blutak or any other cheap ones from Walmart between MDF shelf and the metal frame.

And now you have a fairly decent rack.

The HRS SXR isolation rack is far and above better than any rack I've seen. This isn't a cheap rack but its milled better than anything out there. The company is Harmonic Resolution Systems. I don't own one but know someone who does and it's one serious piece of gear.

My three racks are all standard big box store fluff.
I found them, and paid like $150 each for them.
Filled the square section tubes with dried sand. use butyl rubber bottle stoppers under the feet to dampen the glass shelving. I also 'wedge' which is make the equipment tight between the shelves, having dampening to the underside of the shelf above from the equipment below.
I am happy, and they will last me the rest of my life.
Primarily the good news is I have my racks away from the speakers along the side wall.
So the vibration problem is seriously reduced.

I KNOW this is not answering the op questions, but for others it may be interesting.

Check out pARTicular.com they make excellent racks. semi and fully suspended.

The best racks I ever owned were the old Zoethecus units. I regret ever selling these...

For small (3-4 shelf) units I have had pretty good luck with the Salamander Archetype racks, the ones with the screw thread leg posts. They are a PITA to setup, but they are pretty good if you don't overdo it. They definitely require the optional spike feet on carpet.

Timbernation makes great stuff - very pretty and well-made. I have used his racks for audio shows in the past. The problem is that his solid construction makes the shelves highly resonant. You will need some sort of damping or isolation treatment for most analog gear.

Lovan racks are pretty good for the price, but you can do better. I have used the three-legged racks before (I don't remember the model and ended up throwing out the thin shelves. I cut some oversize cutting boards (from Bed Bath & Beyond) to fit and sat them on small sorbothane domes. It worked out pretty well as I recall.
