Most accurate way to adjust for correct vta on vpi classic 1


Looking for suggestions to get correct vta on my classic 1. Right now it appears that the bottom of my cartridge is parallel to the lp, however this is to my eye. I do not believe I'm hearing the definition I'm wanting out of my LP's?

If your arm does not allow for VTA on the fly, it will always be different depending on the thickness of the record.  That's just part of analog. If things sound a little dull, you can try raising the back of the arm slightly or change the tracking force a bit.  The tracking force sometimes makes a big difference.  Some people cannot live with the variables present in the analog world - always obsessing about adjustments until it becomes a source of stress instead of enjoyment.  Just goes with the territory. 
Find a recording that people say is good for hearing the differences when you adjust SRA. Do a search here and elsewhere; there are a lot of suggestions out there. If you can’t find one, take a record of a female singer, recorded without effects, and listen to it over and over ’till you know it very well. I have used Joni Mitchell’s "Blue." Make sure it’s something you like ’cause you’ll be listening to it a lot.
Set your tone arm to absolutely level and listen to the recording a few times.
Read all you can about your cartridge and see if reviewers or users have a consensus suggesting tail up or down.
Change the angle in that direction a very small amount and listen to the whole record. You are listening for the voice and instruments to "pop’ making them more 3 dimensional. Do that again and again in very small increments. If you do not hear improvement soon go back and stay at level.
If your reading does not come up with a tail up or down consensus. You may have to do this in both directions.
