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 hope I'm about done adding to this thread.This is a
popular arm,so I guess it isn't a wasted effort.Now you see why I was so pissed off with the mainstream audio press for not EVER mentioning any of this stuff.Arthur Salvatore sure has my devoted respect!!

Sbrown,Although there has been statements to the slight colorations in the Air Tangent design,my friend took it to the extreme and replaced the standard compressor with his dentists commercial unit.I can hear the laughter.I did too, when he told me of his decision,and I saw it(looking exactly like a motor boat engine,in his spare room).However this allowed more pressure to be applied to the bearing,in effect stiffening it.This cancelled out any colorations and really improved the bass and mid bass.I really don't think any arm can match this level of performance.

As for the 2.2 I am really,so happy with the current performance that I don't care about attaining that last degree my friend has.However when I go to his home I immediately hear that "Breathy Ambient Glow" the Air design affords.Remember,there is NO resonant bearing characteristic that has to be "STROKED".I know some other pivot designs don't have the need for bearing damping,but IMO only,since I am no expert,they also have their own issues.Anyway,at this point I really think this is an advantage of the 2.2!!Tuneability to the max!!

The best way to improve our systems,and I've seen descriptions of many of your set-ups,that look GREAT,and probably sound as well,is to hear other hobbyists' rigs.Live music is essential,but since we know it cannot be reproduced,how would you begin to suspect that something like tweaking out a resonant characteristic would help your own sound,if you didn't hear it elsewhere!

Cjsmithmd, I should have mentioned this,but,my way doesn't have to be exclusively adhered to.I carefully unscrew the bearing cap and place it down,with the fluid facing up,obviously.Then,since I work with such small amounts of fluid,I allow a pinhead's amount to be picked up(from the syringe) with a needle tip or pin.Sometimes I've been lazy and used my wife's bobby pin tips.There were times when my "always hyper-critical" pals showed up where I had to improvise, on the fly,during a listening session,and have used other pointy articles.It is up to you.Just take it off the end of the syringe(sp?).Even if you squeeze out just a light bubble of the stuff.This way you are assured of working with small and exact quantities.Also,REMEMBER to hold the bearing in place for about a minute or two,exactly over the fluid housing,so as not to drip any residue into the arm assembly,or you will hate me!All in all,it is really not hard to work with.I used to "HATE" to touch my stuff,and my sound suffered.

Whew!!!
Oh,yeah!!You put the fluid on the tip of the bearing,you have just taken off,that is now facing up.This is for fine tuning.Originally the fluid is squeezed into the bearing well at the pivot.Don't overfill this.
As you observed, fluid level, the VTF and VTA affect the sonic quality. The tough music passages on the record put more pressure on the stylus than lighter passages. Therefore, the correct setting for complex music passage may not be desirable for lighter music passage.
That is rediculous!Once you have the setting maxed out,and can track complex and difficult passages,anything else should be cake!Remember,what you are looking for is MAXIMUM retrieval of timbre,and harmonics.These fall into place when all else is obtained.At that point tracking is precise,and superb.You should,also have total consistency from one type of music to the next.Unless you want to get a bit NUTS with making changes for different discs.I don't.I mean I want to spend my time listening to music,not errors in set-up.

I think some of you are "Thinking This to Death" a bit.

Just try playing around for a few listening sessions.Then report back.Or better yet,forget about this thread and enjoy your music!!I know I will when my table comes back.

Sirspeedy,

I am grateful that your table has been out of your hands for a while. Otherwise, you would not have had the time to write all you have in the last couple of weeks or so and we would not have the benefit of your experience and insights.

Nice job on your posts and thanks for the time and effort you put into them.
