What I want to say is this: don't be overly concerned with absolute set up procedures!  
 
Cartridge setup is really an art of compromise. There are simply too many variables that defy all  
meaningful scientific calculations. Theoretically speaking, for instance, you'd have to re-align your  
cartridge when you move the vertical tracking angle to suit the 180g re-issues.  
 
Nevertheless, it doesn't hurt to understand the geometry behind, and better still, to make the best use  
of everything to get the best out of the cartridge you've bought. Cartridges are not refundable after all.

What would you do then if you find audible distortion despite strenuous fine-tuning up to 1/10th of a milli-  
meter at the inner grooves?  
---------------------------------------------------------  
 
Move the cartridge to a different arm lor. If its still not working, I would detach the cartridge and put it inside a box and hiding it somewhere in the house, in a drawer, a closet or a wardrobe that doesn't below to me and try my best to forget about it completely.  
 
After one, may be two winters, my CEO could one day scream unexpectedly about a cartridge she has just discovered from her belonging during an annual house clean. By then, my mind would be fresh and surprisingly happy to take up this "new" cartridge that I don't even remember if it was mine or belong to a friend.  
 
Always fancy trying out something new that doesn't seems to belong to myself, ah ah! And by then, my cartridge alignment skill may have improved to a new level.

bobui,  
 
Please bear in mind that most elliptical styluses may not be accurately orientated. A deviation  
of 1 degree is enough to foul all your alignment efforts.  
 
And the irony is, the more expensive the cartridge, the less accurate its diamond is set!  
 
With pivot arms though, there are still 2 points where you would have zero error. If you are using parallel  
trackers, you would end up with almost constant tracking distortion.  
 
What would you do then if you find audible distortion despite strenuous fine-tuning up to 1/10th of a milli-  
meter at the inner grooves?  
 
My method is to twist the cartridge slightly at the head-shell seat. If more offset doesn't help, try the  
other way. Believe it or not, it works.

I mostly concern about distortion when the cartridge is approaching the inner tracks because that is where I sometimes hear distortion when the cartridge is not properly set up such as incorrect over hang. Worst if the cartridge is no new and the suspension has started deteriorated.  
 
When a cartridge is brand new, the stylus tip is sharp and suspension works normal, the tracking ability is high. Alignment issues become less of a problem when compare to a used cartridge. In another word, using your ears to examine distortion on a new cartridge become less obvious!  
 
1mm sound ok to me also. To be honest, most of the time, I just try my best to get the accuracy as close as possible when setting up tonearm and cartridge and sometimes I just repeat the alignment procedure a few times to bring it down to a closer tolerance.  
 
VTA and bias force is where I agree cannot purely base on scientific measure.  
 
Take bias force as an example. The pulling force is greater towards the inner tracks then the outer. There is very little chance a single tracking force can be catered equally to the whole recording.  
 
For effective arm length and overhang, I mostly rely on manufacturer provided figures.

>Did you use the Lofgren, Baerwald, or Stevenson alignment curves?<  
______________________________________________________________  
 
I was just pulling your legs on that one! :-)  
 
These are my thoughts on the issue:  
 
1. With a normal pivotal arm, you can, at best, only have 2 null points. The difference alignment curves just minimize the distortion in different position of an LP. So, if you play many LPs, with different ending positions of the inner groove with music content, then no one set up can be ideal for every situation.  
 
2. According to the setup jig of the Phantom arm, the overhang between 2 alignment curves (can't remember which 2) can be nearly 1mm apart! So, which one is “correct”? The answer is most likely “it depends” on what LP and which track you are listening to.  
 
3. So, I am very skeptical when people tells me they used this super accurate arc protractor, with the lines thinner than the human hair; spent 10 hours or more to align the cartridge, and got dramatic improvement on the sound! Well, unless you listen to only 1 track on one particular LP, any alignment is just a compromise!  
 
4. With the Phantom example about, my thinking is any setting within that 1mm is probably acceptable, so you don't need to be ultra accurate in that setting. Yes, you may hear a difference if you use one track on a particular LP as reference, but it probably won’t be very meaningful when you play other LPs!  
 
5. The VTF and azimuth may be more important factors in a TT setup!

Did you use the Lofgren, Baerwald, or Stevenson alignment curves?  
 
---------------------------------------------------------------------------------------  
The printed two points cartridge fine alignment in the pictures I have shown below is from the Hi Fi News test record. I am not sure if it was based on Lofgren or Stevenson.  
 
The curves were drawn based on each tonearm manufacturer effective arm length and over hang figures.  
 
If I remember correctly, Lofgren did offer two sets of cartridge alignment techniques. One looking more closely to inner tracking error and the other is outer and overall RMS distortion. Right?  
 
I did read Stevenson alignment method a while ago but find that there was not a lot of new discovery that have already been explained by Lofgfren.

Thanks for your input, Daiwok!  
 
Its good to see the growing number of protractors in the market that aim to offer an easy measure on the mounting distance of a tonearm from the spindle which I believe is the fundamental and most basic element of cartridge alignment.  
 
I personally would aim to have the tonearm mounting as close to the suggested distance by the tonearm manufacturer before moving on to make any fine adjustment on the cartridge head shell.  
 
The closer you can get to a correct mounting distance of the tonearm, the more possible and accurate it is for later stage precise cartridge tracking adjustment. The fact that some tonearm manufacturers went as far as from millimeter to micrometer for the mounting distance reflects the importance of a correct tonearm mounting rather than a thing you can avoid taking too serious.  
 
"The more I look closer to the negative impact on cartridge tracking error from pivot arm, the higher the desire to opt for linear tracking".

Bobui,  
 
great post ! in the past I have used a compass as well, other helpful items include extra long plastic rulers where you can drill holes to mount.  
 
My only comment is these measurements from the manufactures such as the mounting distance being 307.4mm and for Schick its 304.75. I mean can we really measure and mount .XXmm ? things brings up a couple of questions:  
first of the stylus tip is extremely small, the actual trace of the very point of the profile, much smaller than .XXmm IMHO so the mounting is even refine that what we are measuring to.  
 
No 2 cartridges are the same in terms of cantilever to stylus relationship. My view has always been that manufacturers provide guide notes. To accurate mount a cartridge whether alignment, VTA, VTF, SRA, even setting put the tonearm counterweight etc, are just to allow you to get good sound reproduction, not necessarily the best which fits your system. Each arm and cartridge combo needs to be fine tuned. I believe Master Limage spent over a month tuning his A90, this shows some serious dedication !  
 
I don't disagree with him. fine tuning is torturious and painful, but the benefits can be reached. Having said that, there are also several standards used for cutting records, so sadly what may work for one cutting, distortion could be troublesome in others. Hence linear tonearm is the solution, but we just love pivot arms don't we ?  
 
ok overhang, over hang serves 2 purposes, one that if the record has finished and you fall asleep then the stylus does not class with the spindle. The other is fine tuning of distortion, The relationship can be calculated. Check out the link below.  
 
Some people may say analogue is a pain in the butt and inaccurate, but the journey is much more fun !  
 
Will catch you bro when I am back in town ! right now I am in CADIVER state for a week ! 8^)

Final step  
 
 
Here is the final picture showing the alignment for outer ring.  
 
To me, this is the most simple method I prefer for cartridge alignment. Very basic and effective for even if I want to swap to a different cartridge. I simply use the same curve. One curve for one arm!  
 
Old fashion to you? Feel free to comment and advise.

The printed rectangular lines are for final alignment of the cartridge to make sure the cartridge sits as close to parallel to the groove in the outer as well as in the inner groove.

Step two  
 
This curve you see below is most essential for cartridge alignment and is the path where the cartridge read the LP groove from outer to inner.  
 
I have drawn two curves. One for the Morch 12" arm and the other for the 9" Alphason 100R. The Alphason curve is steeper and further out from the spindle towards the inner groove indicates it has a greater tracking error than the 12" Morch.

Step one  
 
Draw a straight line across the center of the spindle and one end of the line need to go far beyond the 12" platter. The purpose is to locate where the arm should be mounted from the spindle.  
 
I am using Morch 12" UP6 arm and the tonearm mounting distance from the spindle should be 294.1mm from the manufacturer. Measure 294.1mm from the center of the spindle and mark it down on the straight line. I call this the mounting point and in most case it is also the position of the tonearm pivot/vertical bearing.  
 
*Effective arm length is derived from tonearm mounting point/distance + overhang and the overhang distance for Morch 12" arm is 13.3mm  
Therefore: 294.1mm + 13.3mm = 307.4mm is the effective arm length  
 
Next is the draw an arch/curve of 307.4mm from the mounting point.

I once met a colleaque (blonde by the way) in UK, she was from Darwin. Typical agenda, we left the office around 5 and she would down a bottle of Savingon in happy hour, then proceed to dinner at 8:30pm and down yet another bottle of something. Hit the dance floor at mid-nite and by the time we finished at 4:30am, she probably down another bottle plus a 6 pack of Barcadi cocktail, & me, I lost the ability to count hours ago ...

Just the pipe organ took six years to build and tune. Its the world's largest fully mechanical organ. As you may have heard that the Sydney Opera House is a vastly over budget project that took more than a decade to build.
