Rack for Pass XA30.8

I always have to sit my XA30.8 on the floor, or on a large chopping block because it won't quite fit on my Pangea  rack.  Can anyone suggest a rack with three or four shelves that is wide and deep enough to comfortably fit the amp on the bottom shelf.   The amp is about 19 and 1/2 inches wide, 21 inches deep ane 8 inches tall.  Thanks,

Salamander synergy racks. Fits on the bottom shelve.
Mapleshade maple racks are perfect for large amps.
Mapleshade for sure. Especially the 4" thick ones
Solid Steel S2-3 or 2-4
Solid Steel S3-3 or 3-4  (Deeper shelves and more heavy duty)
