Thanks!
Me and a local audio friend got those shelves from the container store about 10 or more years ago. I started on a shelf system and my 100 year old house's wood floor is like a trampoline. When I had my 20lb canine buddy Hershey, I could feel him walking through the house from the kitchen to come see me. I also got lots of bass vibrations that would resonate through the turntable and stylus and create a horrible bass tone in the room at certain frequencies. This solved both issues.
