I am using a Twin 40. With two six shelf stacks, it accomodates all my stuff. I have a larger turntable and a digital source on the top shelf. I don't have any side panels or doors due to concerns about ventilation and the need for regular access. Also, I have some components that extend past the edges of their shelves, and a side panel might not allow this.
The corner post architecture is effective for stable support. The rack is in a corner of the room, and I have braces between the top shelf and the two adjacent walls. The result is a very rigid set up, especially with my heavy amps on the bottom level. There's absolutely no swaying or low frequency sensitivity.
True, there's no real vibration control, and I have thought about special supports or platforms like the Gingko Audio and Vibraplane systems but haven't invested in them yet.
Before the Twin 40, I used two Standesign racks, the Design 4 and 5T, that had shelves attached to single posts in the back of each. I found the post got in the way of cabling for some deeper components. The lack of vertical adjustability of shelf positioning was inefficient for allocating vertical space. Finally, the shelves would sag/dip down under the weight of my heavier equipment. In the long run, these negatives offset the positives of a visually attractive design: with the higher shelves indented/slanting backward and no vertical rack elements visible from the front -- the shelves appearing to float in the air with no support.
