If you want a real 19 inch relay rack (basically they're kinda ugly for living room) and you want to support your heavy amp, but not on the bottom, MIDDLE ATLANTIC and others have shelves which will hold over 100 pounds. I didn't want glass shelves for my "stuff" so in one installation at home I took a surplus 19" relay rack from a TV station ($35) and put "firring strips" on it and to those nailed with brads pannelling, available at any hdwe store. The outside corner trim. Varnished the raw trim. Total cost for the 74 inch steel rack which will hold hundreds of pounds [and, to which the wife doesn;t object] around $80...and it's all vertical so the footprint isn't wide.
