A Question About Audio Racks

I have a question about audio racks that I hope some folks here might be able to help me with. I am currently thinking about an upgrade and wondering if I might get even better sonic results from using a mostly wood rack over the glass/steel combination that I am currently using. I live in South Korea, and we don't have access to some of the more interesting racks that can be purchased easily in North America. That coupled with the currently weak currency discourage me from trying to import. I'm currently using this rack: http://audiodeco.com/product/goodsdetail.asp?no=50&cate1=&cate2=

It's served me well for about four years. I'm considering changing to this one:

http://www.carnivalmall.co.kr/mall/m_mall_detail.php?ps_ctid=01000000&ps_goid=51

Obviously this is all in Korean but the Carnival rack uses walnut with a bed of marble in the shelves. Does anyone think this would be much of an upgrade if at all? The glass in the Audio Deco is very thick with little if any vibration. The shelves are adjustable in the steel frame. The Carnival rack is not adjustable. I would like to have a bit more shelving for components, so I was thinking of buying two of these. Thanks in advance for your thoughts on this.

Check Tpsonic's system. He has what I've found to be the best combination for resonance management. Between shelf and component use Mapleshade IsoBlocks (or much, much cheaper yet and essentially the same material, V-pads from HCAV suppliers), then a brass footer like the Mapleshade HeavyFeet in direct contact with the bottom of the chassis of the equipment. Ideally the shelf should be wood or similar resonsnce-absorbing material.
Best advice so far is to avoid glass, marble, granite and other materials which tend to resonate.
