Your 3009/II Improved is a low mass arm and will work best with the Shure V15 VxMR.
I used to mount my TD124/I with 3009/II non improved, and it sounded okay. Later I went through a series of arms and settled on a Schroeder clone.
The 124 comes alive with high mass plinth, preferably mounted on high mass platform. I find that ceramic ball based footers also work better than brass cone footers.
