I'm seeking recommendations for an attractive audio rack capable of holding a BAT VK-600. The VK-600 is a large beast weighing in at 23 inches deep and 9.5 inches high. This seems to outstrip anything I can find.
How about the Mapleshade racks? The shelves are infinitely adustable and you can order shelves up to 4 inches thick. They will custom build if you want but I think the big Samson rack should be fine for your VK-600. These are on my upgrade list.
Steve Blinn racks can accommodate the BAT, either in a stand alone amp rack or as part of his basic multi-shelf designs. His racks are all adjustable, with thick maple shelves and metal supports. Email him and he'll accommodate your needs easily.
