Wow! So Jon, you're the one that got Marco started on his downward spiral into Audiophile Hades? Personally, I think a highly creative goofball like Jax2 would have found another insanely expensive outlet for his creativity even if you hadn't let him listen to your system in the early days. He's the resident Audiogon kook and comedian!
Years ago, I had one of those wooden 240 disc CD spinners sitting on top of my subwoofer. I never heard any CDs rattling during scenes like the T-Rex vs. Spinosaurus battle to the death, maybe because my whole building was shaking too, but I did notice a few had gotten shaken out of their slots.
You're probably right about the amp case shaking from both physical contact and airborn vibrations. I was listening to my system last week and noticed a slightly hooty sound in the upper bass and lower midrange. It turned out it was caused by an empty box sitting at my feet. When I picked up the box with the music still playing I could feel the vibration in the sides and flaps of the box. Even when I moved it to the back of the room, I could feel it humming along to the tune. I put some stuff in the box and the noticeable vibes had stopped.
Since audio gear is all exposed to airborn vibrations, my guess is the only thing you can do to reduce the buzzing if your wife insists you place the DNA on the Vandie, is to create isolation between the two units. Granite or a two inch thick piece of hardwood with the kneaded eraser tweak I mentioned might help a bit.
And, since you're an old friend of Marco, maybe he'll lend you some sand or even let you in the sandbox. But don't go digging around for those nudie girl playing cards, who knows what else he's got hiding under there.
Good luck,
Dean
