Graham tonearm tweaking


I have recently finished my Teres turntable project. I purchased a used Graham 2.0 for it, and installed my Clearaudio Discovery cartridge last weekend.

My question is, I have been reading the forums here regarding the damping levels on this arm. Could someone who has experience with this outline the method that they use to tweak the level to suit the cartridge? Please go into detail as to what you are listening for at each stage of the adjustments. Do you key in on the bass, or listen for treble?

I am looking forward to finetuning this arm and want to put in the effort needed to get it to its best sound.

Thanks guys, Brad.

I was the one who started this thread topic back on 9/30/04. Many responded, but it was SirSpeedy who rose to the occasion and has developed the most informative and detailed analysis regarding this tweak. My hat's off in tribute, SirSpeedy.
This 'tweak' - damping fluid amount, can make or break the Graham for many people, it seems. Thank goodness we have this venue, Audiogon Forums, to make known this all too important factor. I wonder if too little information about this point is also included with the new Phantom.
Sirspeedy - The mainstream audio press may have dropped the ball regarding Graham fluid damping, and its affect on bringing out the best in that arm, for a variety of reasons.
Trusting that the designer knows his product well, it has not been made very clear in the instruction manual how to adjust the fluid damping for its optimum. Most owners and reviewers put in an 'average' recommended amount and let it go at that. Although this arm has been "covered extensively", as you say, I am not sure if anyone other than yourself has devoted as much research into the critical effects of damping fluid amount. Certainly no reviewer has. The arm has been seemingly judged on its "follow-the-manual-setup-recommendation" merits. This arm in particular, or perhaps unipivots in general, may be very sensitive to damping fluid adjustments, more so than arms like the SME V. Now that you have 'unearthed' the method of tweaking the Graham damping fluid, it still will remain for most a daunting process of trial and error which many may not want to bother to fiddle with, especially given that a change in cartridge choice may require a change in damping fluid amount,.....again.
Hopefully some mainstream reviewers, and maybe even the creator, Bob Graham, will bother to take the time you have and investigate this topic and publish their results.
Thank you for your invaluable contributions.
