Thanks for the comments. I am going to make a few changes to the original plans based on my experience when putting this one together. I'll get them out sent soon.
Mike, the is no wobble or sway. I used one inch threaded rod and the holes were milled to 1 1/32". I would have the holes milled to 1 1/16" if doing again for easier assembly. Baird Brothers did a great job, those shelves when stacked on top of each other lined up perfectly with rods inserted in all four holes. No way that accuracy would be possible with a drill press one at a time in a home shop. Every once in a while some of the nuts get a very slight tighten so I'd add lock washers if doing this again. Note that some commercially made designs have 5/8" rods and 3/4" holes. I originally had a McIntosh MC 352 power amp on the bottom shelf with no problem.
The 275 power amp sits on a 12 x 18 cutting board. The laptop is on a temporary shelf made from scrap wood. It got it off the TT dustcover (also home made) and also provides a visual for more shelves should I get crazy and go to a separate DAC and two box pre-amp.
The 2" pads underneath the components came from from The Supply House, a plumbing supply place out on Long Island; about a quarter each.
