Audio racks that can handle heavy components

One of my Steve Blinn racks is supporting a 150 pound (approximately) BAT VK-600SE power amp and looking good doing it with 2 inch thick maple shelf supported by a beautiful, extruded aluminum structure.

I'm Looking for something more....furniture style.  Gotta keep the wife happy after spending $30k on a freakin' stereo.  (yes, we have an expensive hobby but it's no worse than building a muscle car.  Once you start down the rabbit hole...)

We have a Dutchcrafter solid wood bookcase and I need something more vertical.  Thanks to everyone who posted here.  Lot's of good info.

Not as great a comparison as it seems - Ferrari used to send cars here that had no paint on the underside of fenders - they started rusting when they left the factory!  Undercoating was pretty much unknown in Italy.

Solidsteel. Since 1995 and again in 2024.
