Cart adjustment, that moment when you nail it!

Dang, after futzing with my analog system, and getting it “ok” but with some distortion here and there etc, FINALLY got the thing dialed. All I can say is WOW... Lot’s of trial and error, tiny adjustments, etc. and then ding! Nailed it. Finally! Just awesome. If you are in the tinker mode, keep trying, you WILL get there. It’s worth the time!
What was your last tweak that “nailed it”?
Until next week or the next bad recording. 
Mostly adjustment. I got super specific with the alignment it was just a tiny bit off. Made all the difference. 
Yes, and adjusting the cart alignment to the head shell. The SME V doesn’t have an azimuth adjustment per se, but it can be tweaked a tiny bit by making sure the arm is in perfect alignment when tightened after the VTA adjustment. I thought I was doing things in tiny increments, but turns out those “tiny” adjustments were still too big. It’s tedious, but it makes all the difference. Probably still more precision could be had with regard to azimuth, with shims etc, but I’m good for now.
