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.
