I have two... both from the Synergy Series. One is an upright "Single 40" and the other is a "Triple 20". The shelf sizes are adjustable but the basic 'unit-size per shelf', if you will, would hold an amp about the size of an Odyssey Stratos. They also offer some nice touches like metal screens for ventilation, solid industrial casters, and removable backs that are designed to accommodate cables and chords.

These really are quality pieces... for MDF-based furniture, that is. For the price, I doubt you could find any better.... different but not better.
