What three shelf stand should I purchase?

Adona is one good choice, but Core makes really nice looking stands as well.

I like the Adona...checking it out...do you have one?

WAF ?? I doubt your wife is all that.

Wood stand is a must, no glass or metal. Wife needs to choose the wood color, this gets her involved. Must also be open on all sides, no doors, air flow is also a must to keep the tubes cool. Consider using a laptop fan system, they are very inexpensive and can be run with a simple usb power plug.

Recently purchased Quadraspire and was taken back by how much better it is than my Target stand. Would have never believed how much more stable the soundstage became and how much more controlled the bass is. It was truly an epiphany.
