Keep in mind that the performance of my AF1 is even superior to that of Nishakawa-sans (No disrespect) as he does not have active isolation. It is a significant audible improvement with active isolation. Many times I have forgotten to turn the Table Stable on....only to realize the sound isn't as transparent, quiet and defined as I remembered. I look over to the TT and see the Table Stable off. When I hit the button, the magic comes back.
Until you get the Vertere Reference Tonearm, you are still only utilizing some of the potential of the AF1.
