You say 16/44 shouldn't have been attacked?
I say 16/44 shouldn't have been released to the public until a decade later, at least, as far as digital recording was concerned. They jumped the gun for financial reasons, of course.

I suspect that Sony/Philips did not believe they were 'jumping the gun' on technical grounds. I suspect that they felt they held full knowledge and control of the technology. It's hard to fault them too much, I think. To do so would be to also fault the inventors of the 78RPM vinyl record. Vinyl technology improved after that, just as technology has for digital. To me, the biggest technical sin, because it was clearly understood as a violation of sampling theory from the beginning, was the utilization of half-band FIR anti-alias filters. These simply allow Nyquist to be violated and permit HF alias products to be permanently folded in with the audio signal. I suspect the practice of utilizing half-band anti-alias filters for recording largely continues today. Perhaps, T or someone else who knows more about this than I do, can speak to this.

Are you asking if they exist? If so, Indeed they do.
By the early 40s some standard groove 78s started to appear partly because shellac was hard to get. They are unbreakable but less tolerant of heavy tracking older record players. They are much quieter than shellac.
In the '50s microgroove 78s were made. One label was Audiophile. I have several. They were of course mono. For sound they come close to rivaling such records as Sheffields which came decades later.

Well there's still lots for me to learn after all these years it appears.
I was aware of a few 78rpm vinyls but these were just microgroove records which spun at 78 usually for gimmicky purposes e.g Moby Grape in 1967. There were also some more recent vinyl 78s associated with Robert Crumb I think.
Thanks so much for letting me into a little known corner of recording history.
