I added a second arm to my JVC QL10 (TT101 and JVC QA7045 arm and solid particle board/wood plinth) using a bracket of my design screwed solidly into the plinth, and a Micro-Seiki AX-6G arm-board. As you may know the arm-board attaches to a post on the plinth and is swung into place and tightened down.
The new board sits almost an inch above the level of the plinth - it had to swing in over the plinth to achieve proper overhang. This left me with the arm too high. So to maintain VTA I had to raise the platter. That requirement brought this thread to mind.
I raised the platter by unbolting the TT from the plinth and supporting the nude TT on three Audio-Technica feet but left it in place in the hole in the plinth. The plinth is on aurios/tip-toes, and both tonearms (epa-100, QA-7045) are solidly mounted to the plinth.
So now I have a nude TT101 surrounded by two arms on a heavy wooden plinth. Initial listening tests are very favorable. I was quite skeptical of the nude idea, but I must admit a veil has lifted as have my doubts. I can only surmise that the motor was introducing vibrations to the plinth that were picked up by the tonearm. I was very happy before, I am happier now.
I hope the pics make all this a bit clearer:
