You and I are at a similar stage right now. We should compare notes. As luck would have it, a bloke in the next village had an extra tube of 30,00cst fluid for sale so I had the chance to try damping on my arm this past weekend. And quess what? The sound is cooler, darker, and heavier. While I appreciate the heaviness the fluid adds to the bass, I miss the the "lighter", airier sound of the arm without damping. Worse, the sound is coloured, like some resonance has been added to the upper bass/midrange. So my first foray into damping is not going well....
Then, a revelation: According to the Mission manual, I should be using the heaviest paddle to match the compliance of the Shinon cartridge. So why would a heavier paddle be better when the slim one I've got now sounds already overdamped? It's not the damping, stupid (I says to me self), it's the rigidity
! Stiff suspension = stiff paddle. Since I don't have the biggest paddle on hand to try it, I'm now on a mission (pun intended) to find one, or make one if necessary. I'm hoping this will fix the colouration, as I'm convinced it's caused by flexing in the thin paddle.
Despite the shortcomings, the small sample of records I've played so far seem to exhibit less of the mistracking behaviour, at least where the occurrence was marginal to begin with. If it turns out that the stage is still too dark with the large paddle, I'll try an even lighter fluid, like silicone oil.
If worse comes to worse and I find I can't live without the incredible lightness of being that is the undamped Mission, I have one other possible solution to improve tracking.
I wonder if anybody has tried plugging the gaping hole in the headshell with a dowel of brass?
