Emaidel, I have similar issues with the RDC cones I use under the Planar 2. I use 2 one by motor to drain vibrations and one under the left corner since it is ever so slightly taller and levels the table. I recently dug out my old AT isolation feet. I bought them in the 80's and I have never tried them with the Planar 2. Now that you have me thinking about isolation I am going to check them out.

I am going to order the Pangea and try them under the Krell. I will also try them under the Marantz SA8001. I am curious what benefits I will hear. When I bought my maple stand I was impressed by the increase in clarity from the weight and solid build. I am interested in any further improvements I might experience.
