Amp Stands - Wood or Stone

And there isn't really any true "isolation" possible on the planet earth

I've experimented with stands and footers over a number of decades, I've probably tried virtually every kind of material out there. Only you can determine which solution best for you, this is part of tuning one's system. In general the material used will kind of tell you what to expect, soft delivers softer more diffuse sound, hard will tighten up things. I've also found a rather unique solution for some of my equipment in using high test monofilament fish line hung from custom built stands, this closest to no stand, footer solution I've found. This delivers most natural timbre, tonality, micro and macro dynamics, natural decay, etc. This method allows the most sympathetic movement with vibrations, and the least editorializing of the myriad solutions I've tried.

See if you can get some of that fancy Cardas wood but beware, if the price per inch is equal to what they charge for those tiny cable supports (that do nothing for the sound), you'll be shelling out big $$$.

It sure does seem that if you have access to both stone or wood 🪵. One is stuck in the proverbial situation where you get to try both and see what happens. Good luck 🍀 in the search for the best.
