Jonathan, Thanks for the suggestion. The arm is a 4 point and I believe the effective mass is 13 grams. I am not using any damping at present, perhaps I should try this as well.
The first digital scope was the Dinolite(200X), the most I could achieve was about 150X magnification because the diameter was large and therefore I could not get it close enough to the stylus to focus at higher magnification. I then got a Supereyes (500X) which has a much smaller diameter and can get in close. The software was not very good with the Supereyes, and I was unable to import the pics into the Dinolite program, which has easy to use measuring tools. So next was a print out on A4 paper and a protractor. In the end I gave up. My SRA was anywhere between 96 and 94 degrees depending on where I drew the lines. Now that the arm is truly level the base is even higher than when I did the measurements. The trouble is that there are so many variables with the photograph and the measuring, I think the results are likely to be misleading. everything has to be exactly 90 degrees and parallel, and the most difficult thing is to define the surface of the record or CD in the plane of the cantilever, or at least that is my experience.
When I tried to set SRA I was missing the highs and the bass was a little overwhelming, now the detail and highs are spectacular, and with that imaging, depth, and sound stage are all superb. Some real experts in the States measured my photographs and came up with 94 degrees, so I was convinced I needed to lower the base of the arm more. Now I can hear that it is "right", which was what everyone was telling me in the first place, my photographs must have been skew! Garbage in garbage out:)
