Chakster wrote that Oswald Mills Audio plinth is made of graphite. That is incorrect. They are made of Pennsylvania slate. Slate and graphite are two different things.
Also, perhaps paradoxically, use of a heavier counterweight could have the effect of reducing the effective mass of the tonearm overall. This is because the effect of the counter weight on tonearm effective mass is proportional to its distance from the pivot-squared, times the weight of the CW. Thus the distance from the pivot is dominant. And substituting a heavy CW for a light one will bring the CW closer to the pivot, all other things being equal.
I agree in principle with what Miller carbon says about having a direct connection from the cartridge all the way to the input of the phono stage, but that is only an ideal goal and certainly not a necessity. I do insist upon it with very low output moving coil cartridges, but I cannot hear a difference with higher output moving magnet cartridges, for example.
