Graham 2.2 traking force, do you use more?


To all graham 2.2 users.
What cartridges do you use and what tracking force do you use?
Do you apply more tracking than the cartridge manufacturer states?

I have started to notice that VPI uni pivot users apply more tracking than the cartridge manufacturer suggests.
So as an experiment I am tryiing an additional 0.2 grams over the suggested maximum of 1.5 grams on my van den hull condor and it ain't bad!

Looking forward to the feed back.

Dear Tris,
That's one of those things that can work equally well, but some may "feel better" if they have more fluid of a lower viscosity than doing it the other way. Damping is damping, and I think the arm will not care much.
In the case of the Phantom, fluid damping is only part of it; the rest is taken care of by the magnetic stabilization system Magneglide. In this regard, there is really no reason to dilute the fluid to change damping levels, and putting in a little more (or less) standard Phantom fluid will be just fine. - Bob Graham
Dear Zargon,
By all means, use a range of force up to 2.2 grams if necessary. The 1.8 is the "standard" setting recommended by Immutable, the manufacurer of the generator we use (we make the cartridge body and supply the 4-N silver wire ourselves)... We have found it works very well at a 2.0+ setting, and with no problems with buzzing or increased wear. As I mentioned in my post, tracking a bit (but within a reasonable range, of course) heavier is actually kinder to your records than the psychologically-tempting lighter forces which may result in poor stylus contact and groove rattling (chiseling...!)
I just happened upon this dialogue, so thought I'd add a thought or two: the degree of damping fluid in the 2.2 (or any damped arm) is subject to variations and personal preferences. Too little damping and you get one kind of sound (possibly brighter); too much and things may get sluggish. That's a generalization, of course, but it does get to the point: everyone will have an opinion!

As for tracking force, I have also tried raising it a bit for different cartridges, and have found that tracking on the higher side OF AN ACCEPTED RANGE will tend to give better performance. What's the "accepted range".? One that will place the coils in the center of the magnetic field for balanced output, combined with placing the stylus tip and cantilver at the desired angles.

Here again, a compromise must be worked out, and if you increase the tracking force (thereby changing the SRA), you may need to adjust VTA to compensate, and always keeping in mind the need to keep the magnetic system in balance.

In the 50's and 60's, cartridge manufactuers were in a race to have the highest compliance and lowest tracking forces, and many consumers believed that a 1-gram force would be less wear on a record than a 2-gram setting. This would be true ONLY if the stylus tip tracks properly and does not rattle around in the groove; otherwise, the lower tracking force would cause a severe and permanent increase in record wear. That's still true today, and a few tenths of a gram tracking force will be much less an issue in saving your records than a cartridge (or arm) that does not track properly...

OK, with all that said, any debate of the 2.2 refers to an older technology that was, at the time, our best shot. Now, with the Magneglide (TM) stabilization on the Phantom B-44 Improved, there really is no comparison to the 2.2 in any meaningful way, especially in the mechanical terms of lateral stability and neutral balance. In this regard, the B-44 really behaves like a gimbled arm, due to the very strong stabilization force of the Magneglide system. In it's present Improved form, the B-44 really should be discussed entirely on it's own, with no assumptions whatever to be made from experience with the 2.2 and earlier arms. Comparisons to other arms - excellent as many are - is encouraged. Musically, this arm will perform on a level never imagined from earlier designs....

Best wishes to everyone..!
