I like HiFi Racks, they will manufacture the shelf sizes you need and the right leg lengths so you can get the right rack mix for your kit.

Also they are extremely sturdy and can easily support heavy amplifiers etc. or of course Meridian DSP7200HC speakers should you have one.

Not cheap but will last a lifetime.
