Adjusting SRA using macro lens vs microscope


I have ordered a USB microscope to adjust SRA after reading Fremer's article. Meanwhile, I took some pics of the stylus with non macro Canon L lens (handheld) and can visualize the sharp triangular shape of the stylus and the record surface. It is only reasonable to assume that with a tripod and macro lens, the image would be much better.

Since many audiogoners are expert photoghraphers as well, anyone tried this?

Doug,

Thank you once again for being an informed voice of reason. This thread is a nice counterpoint to a thread in another forum entitled "Why Some Audiophiles Fear Measurements". It's not that some measurements aren't useful (they are), but it is human nature to attach a false sense of security to a measurement. An interesting take on this subject is "The Tyranny of Numbers" by David Boyle.

As Doug points out, does anyone think fixing SRA at 92.1 degrees really be any different than 92.0 degrees if you own a large record collection?
