Help Me Choose Timber Nation Rack-- All Wood or Threaded Rod?

Not familiar with Timber Nation. Instinctively I would most likely take all wood. But it is hard to be sure without direct comparison.
I have a Salamander with rods, MDF shelves not hard wood, and I can tell that it rings. When I put the equipment on good cones on hardwood floor instead of the rack it sounds better. My turntable in on a 3" maple block on cones on the floor. I don't have much of a floor vibration.

I have two of his racks, both solid wood. No more need for fancy feet.  The shelves are so stout either the all wood or threaded rod will give you isolation!

I have an all wood Timbernation rack made from Walnut. I am very happy with the rack. I don't have a threaded rack so I can't comment on the difference.
