You have omitted telling us about the major deciding factor. Does it sound better one way or the other?
If it sounds the same either way then you may prefer to have a nice symmetrical visual presentaion. Otherwise the answer should be obvious to you.
How it sounds, as pointed out by PAR, is always the final determinate, and it's my experience that Azimuth is at least as important as SRA.
Have a record with annoying sibilants as do I, like that horrid Diana Krall Classic LP, "Love Scenes" or Alison Krause/Union Station "New Favorite"? Sibilants were tamed on both using the JMW Azimuth adjusting ring.
I found that leaving the inner Allen Key just loose enough so that moderate pressure was required to move the ring with the outer key loose, just as you do with one of the headshell screws when adjusting cartridge overhang, eliminated overshoot and the need to tighten that pesky inner key every time you wanted to try a setting.
I also pass along the function of the cardboard sleeve the Azimuth Adjusting Rod arrives in as what, in woodworking circles is known as a "Winding Stick". Place the Rod in the headshell groove and the cardboard in front of the cartridge on a record then sight across the top of the cardboard. You will either see the left or right end of the rod visible above the cardboard indicating out of alignment or the rod clearly level in relation to the cardboard.
Keep in mind that for a variety of mechanical reasons, the winding sticks will only show you in the ball park.
That done, begin the listening test, and remember, if it were easy, everyone could do it ;-}
you can not rely on the horizontal position of the VPI rod. It nearly never tells you if the setting is correct.....perhaps in the ballpark, but not in the best seat.
Thanks for the reply. Unfortunately I've only listened in its current configuration. Your suggestion is a good one, though I was hoping somebody would tell me the tilt didn't matter since I'm not anxious to fiddle with the azimuth on the unipivot again. I know there are tools to help with this but I've been too cheap to buy one so far.
" I'm not anxious to fiddle with the azimuth on the unipivot again"
I sympathise with your feelings on this knowing VPI unipivot arms myself (well, one of them). You could try one of Soundsmith's "Counter Intuitive" gizmos. It won't tell you what is the correct azimuth but will allow you to adjust it whilst retaining VTF or vice versa.
"If you prefer you can rotate the azimuth ring to set azimuth instead of rotating the counterweight."
I don't know if all the VPI tonearms have this but it makes azimuth adjustment easy.
Have Fun and Enjoy the Music
"Still Working the Problem"
Yes. My arm does not have the rotatable azimuth ring. I'll probably pick up the Soundsmith gizmo eventually but I guess I have to suffer for a while first. :)
