I use a pair of Finite Elemente Racks, a Pagode Signature and Master Reference in black:
Shelf height is completely user adjustable based on size of your components.
There's lots of pseudoscience about vibration damping and all that, I just bought it because it looks awesome and is solid as a rock. I've always wanted to try Billy Baggs custom racks with the granite or thick frosted glass shelves but I just think it would be prohibitively heavy. I visited a dealer who had a Grand Prix Monaco and was unimpressed visually. If you're absolutely insane and burning money with fire just isn't fast enough, a Magico M-Rack can be yours for $30-50,000,
Some other names that come to mind as solid but that I haven't personally had experience with are Steve Blinn, Adona, Box Furniture Co., and Solidsteel. Most of these items are much more expensive than they need to be, something from your local store usually works just fine (possible exception -unless you're dealing with turntables.)
The best headphone stands in terms of functionality + looks are the Rooms FS Stands available from Thomann.de, No compression of pads and dispersion of weight over the entire headband without stretching anything.
