I have considered this, although it would be a huge commitment. Beyond traditional pier and beam construction, each piece of sensitive equipment would get it's own individual concrete pedestal, going deep into the earth, below the house. The rest of the living/listening area would be constructed in the normal fashion. Finishing out the pedestals and the living area floor to the same height would be tricky. Then a seal between the two individual surfaces would be needed to fill the void . With the equipment on their own individual solid concrete blocks, the entire house would be de coupled from the equipment. I know one high end manufacturer that uses this design in his home. Unfortunately I have not had the pleasure to visit and view the project myself.
Hanging Audio Rack?
I was thinking again, sorry. I'm wondering if any of you have tried to hang your equipment from the ceiling. I know turn tables have been hung, I had one in my dorm. What I want to know is if anyone has had experience trying to hang a steel or other material rack. If you did, how did it work, what were the sonic benefits? If you haven't tried it, do any of you have thoughts on what might be expected? I'm thinking of four point suspension from the ceiling joists using as thin of wire as possible. Thoughts?
