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.

I have an all wood Timbernation rack as well but cannot comment on the threaded columns performance. The all wood is so solid that if an earthquake were to hit, I'd huddled up against it and keep my head low.

All the best,
