VTA adjustment for VPI 10.5i tonearm

Thank you both for your suggestions. I'll try sighting along the headshell instead of the armtube.

Thanks again for your responses, all useful information. I started experimenting last night, slightly raising and lowering VTA and listening with a friend. I do not obsess over it, just want to maximize the sound quality for best overall sound quality and leave it there. Small changes can make a difference!

I'll try that. I was making pretty small changes, not nearly as much as you suggested. A large adjustment in VTA can affect VTF, so I'm aware that this has to be checked. Thanks for your input!
