@mijostyn , I greatly appreciate your thoughtful post.
I take your advice about VTA seriously and without offense. If it's a delusion, it is a persistent one, decades long, but perhaps confirmation bias is operating in more ways than one. I'm going to try again with my current arms to see if I can be satisfied with a happy median VTA. It would certainly open some doors.
Maybe, too, it's time to set VTA with a microscope and see what's what. I doubt I'm comically off but there's one way to find out. Do you like the WallyScope? Seems pricey but perhaps justifiably so. Other recommendations for a scope with good software for drawing and measuring angles would be greatly appreciated.
Over the course of a very long conversation, Thom was remarkably careful about specific arm recommendations, probably because he shares @lewm's caveat about cartridge and table synergy with any arm. The custom (as opposed to commercial) Schoeders came up a few times, as did the Kuzma 4P-9. For my Technics plinth he thought his hybrid 11 would be great option, if I could get over the VTA thing. If you're unaware, he mounts an 11 armtube on a 9 base, and does so with Frank's blessing and apparently good results. Given the 18g eff mass of the 4P-11, he thought the 19g of the 4P-14 was a misprint on the Kuzma website, so he is emailing Frank for confirmation. I mentioned the Triplanar 12 and he deflected it. MSL is a fairly new line for him, so his hands-on experience with them is in the early stages.
