Heavy duty amp stand, Sonic benefits?

For what it's worth, Sound Anchor is a solid company that makes really good stuff.

It will definitely benefit whoever you buy it from.

100% YES is the answer. Those cheap stands will vibrate whenever your high end system is providing sublime pure sound. This induces capacitor jitter which degrades sound as vibration effects capacitor output. For those of us smart enough to have all tube systems the same can be said for the induced filament vibrations which also effect output. I use poured concrete stands and then have special isolation feet beneath the stand and each piece of gear. I only do this in a room with a concrete floor and the outstanding results speak for themselves.

Really interesting comment.

My basement has cement floors, of course, and I think there’s benefits of this versus wooden floors but I could be wrong.

Benefits to tube amplifiers is more interesting

My Patios InPol Heritage integrated sits atop a heavy (non-audio) wooden rack.  
the stand is two IKEA APTILIG bamboo boards (1-3/4” each) separated by Herbie’s  Giant Fat Dots with Herbie’s Giant Fat Gliders under the stand.
