DBx was seen as competition for the original DOLBY for consumers. A buddy of mine had the original Advent outboard Dolby which indeed was a PIA to get working properly.
And Yes, you had to basically calibrate for a given tape. At that point? Probably best to 'stock up' on whatever you settled on.
Later, with built-in Dolby of cassette decks, I had best luck with TDK SA or SAx tapes. But no way to 'calibrate'.

One way around your objections is to limit frequency of operation. Say from 5khz UP. I'm not certain that the various versions of DOLBY were not so limited. My one venture into owning a cassette deck had Dolby 'A' and Dolby 'B'. I think recording studios had access to the 'C' and 'D' versions? According to this article, an alphabet soup of Dolby once was used, with only some still surviving. www.soundonsound.com/sound-advice/q-what-different-about-varieties-dolby-noise-reduction |

Keith, what resolution do you use to rip your vinyl?
Oh, and as far as "To me, that's: "a complicated uphill battle, that nobody's got entirely right so far, and that seems unlikely to ever be gotten 100% right"."
No complaints with that description at all sir! We just have a different attitude about it.
Trey

One possible solution to the analougue noise reduction problem lies thru computers.
If you had the right software, and a large buffer it turns into a 'computationally intensive' problem.
And with a solution.
When ripping vinyl, the Best you can hope for is to duplicate it, warts and all. That includes surface noise and dynamic limits.
The limits Keith speaks to can be heard by some systems 'breathing'. It just don't sound right.
Click / Pop reduction should be possible without damaging the source material. Maybe even hiss?
