Graham Phantom Anti-Skate. Is it effective at all?


I've had my Phantom Supreme over a year now, and for the most part it's been a pleasure. Beautiful build & sound; awesome VTA and azimuth adjustments. My main hangup had been the headshell; getting a Koetsu to sit flat on the 10" wand seemed impossible because the correct overhang pushed it all the way to the back, behind the main headshell points of contact. Finally I just used 2 plastic washers as shims to get a nice flat mount.

Now my main concern is the anti-skate. I'm not sure if all Phantoms are this way or if it's an issue with my unit. I can't seem to get an effective amount of anti-skate. My preferred method for adjusting anti-skate is to drop the needle in some dead-wax before the label (NOT into a lead-out groove) and adjust so that the stylus creeps *slowly* inwards. With my Graham, I cannot achieve that...it always moves quickly inwards no matter how far out I set the weight. Even physically pushing down on the weight doesn't seem to have much effect in swinging the arm. To me, this seems like the mechanism is not effective, as if I'm running without any compensation. This is very unlike my experiences with a Fidelity Research FR64fx (weight and fishing line) and Clearaudio Magnify (magnetic) -- both have a very noticeably effective anti-skate mechanism, which I can easily dial-in as described above. In fact I just setup a Magnify...it was great!

On my Graham, the pulley & rope system seems to be correctly in place. But without a 2nd until to examine, I can't determine whether this is normal. Could other owners/users of Graham please comment on their experiences with its anti-skate? The situation is OK for now -- I burn hours on my good cartridges very slowly and sparingly -- but I'd rather not have my nice cartridge seeing asymmetric wear over the long-run.

Mulvling....good choice. I don't/have used a/s for years and never have found a reason to use it....however in your case, something is wrong, and I wouldn't subject a high priced cartridge to a wrong setup. When you get your arm working correctly, listen with and without a/s and make your own determination.
Whewe....I have been an exponent of not using a/s for years on these and other pages, only to be rebuked many times over.. Vindication at last...others hear what I hear....improvement with no a/s. ..just to admit to setup deficiency on my part....I got an ap on my iPod touch that is called suface level....it actually buzzes when it is perfectly horizontal. When I initially set up my table I used a carpenters level, and now realize that the little bubble may be off because of parallax error, etc. Anyway, with the aid of the buzzer crying out in perfection, and again using the FOZ to check for azimuth, I am rewarded with an even better picture to the musical event.....Vinyl requires great patience....
Rockitman...A/S is included with tonearms as a selling point....when skating became the new adjustment of perfection, it was hard to sell an arm without it. In truth, A/S is very illusive...there are so many factors that contribute to it that there is just no way to adjust so that it does what intended. Most arms, when set according to directions apply WAY too much a/s . The constant outward deflection of the arm...when not needed...especially with too high a setting, exerts a force that inhibits the stylus and produces a side damping. One wants the stylus to be absolutely free to negotiate its travels.
John ...even your last sentence is wrong. I suspect that there is such a thing as skating force....but it is a very slight, illusive and constant changing force. It is impossible to correct for it and most times it is overcompensated. Why do you say that there is distortion on one channel without A/S ?? If the vtf is adjusted properly, the stylus stays in the groove with no mistracking. The bottom line is that MY arm/cartridge sounds better with no A/S, therefore that is the better way. I tried it (a few times) with A/S, but the sound is always better without it.
Because unipivot arms are balanced on the point of a pin, if the arm is set up properly it will compensate for any nonlinearity elsewhere.
