@ Downunder,
Sorry to hear that you're dissatisfied with my suggestions to help set up your cartridge. I'm also sorry to hear that you're not willing to read up on the numerous articles that provide advanced insight into SRA optimization for all cartridges (not just the A90). If you are uncomfortable with the information being discussed here, then it might be worth it to inquire to your local Ortofon distributor about hiring a professional with test equipment to do it for you.
For the rest of the interested parties who DO wish to investigate the topic further, I would suggest checking the Analog Corner article from Stereophile Sept 2009 and June 2010 issues. They give some very excellent information on how one can use an inexpensive digital microscope to get a side-shot of the diamond and then to adjust the VTA so that the contact area can be aligned properly. The techniques discussed for SRA aren't rocket science - they can be performed in a matter of minutes once the USB microscope is set up and focused. It's even a possibility that you might find someone at your local audio society who is willing to let you borrow one.
Of course, one may also do this by ear, but as expected it does require tenacity.
Even though Ortofon recommends that you get the SRA to a value that sounds best with the majority of your records, rather than adjusting for each one, I don't see why one couldn't spend some time with a digital microscope and record the corresponding VTA settings for a 160gm pressing versus a 220gm (or the values in between, perhaps).
Since I'm rarely on these forums (as much as I love to chat about cartridges), anyone who has additional questions may contact me directly - ldorio@ortofon.us is my email address.
