So I bought a WallyScope...


It's a very nice microscope and the software that comes with it, while I assume off-the-shelf, is excellent.

But here's the thing. At the end of the day, you are still basically eyeballing your VTA setup, and the instructions for the WallyScope have you do two separate observations to reach your conclusion. The first is the angle by which your stylus hangs off the cantilever, and the second is the angle of the cantilever versus the record surface.

I understand why this is done. It's so that you can measure with the record moving to get the dynamic rake angle instead of static, so that's one error that the method corrects for. But at the cost of introducing the compounding observational errors by taking two measurements and then combining them to calculate your angle.

I was very patient with this process. I spent many hours over several days. I even dismounted the scope from its frame because I found a better way to line it up for taking measurements. 

 

And after all of that, I adjusted VTA by listening. Which achieved better sound. This came to me as a revelation, although it shouldn't have.

I don't regret the purchase, but it's a lesson that we can and should trust our ears.

Trust your ears. That's all that matters in the end. Fancy testing equipment might get you there, or not.

+1 on trusting your ears, with so may different variables on each system and components, it’s the only way to fine tune. Trusting your ears, and adjusting things to your liking is a huge part of this hobby. 

Lesson learned. Weird that I needed it.  Hey anyone want a gently  used WallyScope? Lol.

 

I have two USB microscopes, one better than the other for this job. My experience is similar to yours: I can spend ages adjusting, measuring and finally getting it 'right' - but then realising that 'right' is just the starting point as listening always makes me move things around a little more until it sounds the way I want.

I think the advice that generally came from cartridge manufacturers was probably an easier way of getting there: set the base of the cartridge horizontal/parallel to the record surface when the stylus is resting on the record, and then adjust by sound.

I do not have a Wally scope, though I do have a microscope.  For me, it is a tool to get close as well as see where the final by ear adjustment leaves the angles.  Cartridges of the same type (model number) from the same manufacture can have differences, especially in the alignment of the diamond on the cantilever.  It also helps to observe any changes over life of the cartridge.
