Graham Phantom damping fluid level.


Bob Graham says to use enough fluid to bring the level up to the top of the square profile machined on the bearing cap. The square is only about 1/4" in length. My question is, What level works best for you in relationship to this "square" profile?

I have tried only 3 different levels of fluid in my setup (maximum level to top of square, almost no fluid at all, & to the bottom of the square) but can't seem to obtain optimum results so I'm wondering what others use, although I guess it's really cartridge dependent. Is the fluid level super sensitive? FWIW I'm using a Koetsu RSP.

From my experience, close to nothing is the most "true reproduction" but it will vary from cartridge, Phonostage and what kind of records you listen to.
With newer records I would say, forget it, it doesn't matter, because none of them are true in the tone.
I did listen to a Living Stereo 2400, Strauss Waltzes, Side 1, Track 1
Phantom with Zyx Universe, VTA is a little bit higher in the back
The Vienna Blood allows you a view into the performance, a little bit from above, the strings section left is excellent for that, the tone has to go up and down like their bows and you can hear the reflections on the side walls.
When the fluid is too high, the separation of the strings are a bit "muddy", not really clear, a kind of "wall of sound".It softens the tone.
I checked this tone of this performance with 2 other (top) Record Players, For me: nearly nothing
