They are going to have to be wide pedestals to hold a 19" wide component. Also, you have to be sure that they don't get "tippy" with all the weight on top. Low is probably best for this, with wide base, and firm footers like points.
Personally, I'd say just get a Sistrum rack. They are beautiful and artistic looking, have minimal frontal appearance impact, and really do something to improve the sound, instead of just the looks. You can hardly believe how nice these racks look in person. They are not "blocky" looking, but have a very nice sculptured look, with sweeping curves on the shelves, and nice polished brass legs. Really hard to beat for the looks, and you simply cannot beat them for sound improvement. Reasonably priced, too, for a high end racking component.
