Well I wouldn't go THAT far, Jack ..... but I do wish they'd catch up with the times and consider either SACD or BD~A and dispense with those patently 90's codecs!
Maybe not!
SACD/DSD is based on older techniques, Noise shaping and Delta-Sigma Modulation, with the former proposed by Cutler in 1954 the latter by Inose & Yasuda in 1962! 🤓
DSD is a cheap and very digital way to get higher resolutions by massively over-sampling (modulating!), so easy to manufacture on Silicon. 🤪

SOMEONE'S been reading their Audio Bible! True, Dunc, but not to get into the pros and cons of PCM vs. DSD, I'd still much prefer LOSSLESS SACD over lossy DVD~V DD/DTS.

If you can find fault with any of Dutton~Vocalion/Epoch SACDs now's the time to Spill........

And why do I know THIS: My King James Version of the Audio Bible TELLS ME SO!

It was an IEEE 'bible', Oversampling Delta-Sigma Convertors - Theory, Design & Simulation .......... a good soporific!

Properly dithered (possibly packed as is Dolby TrueHD) at least 20bit/58kHz PCM is all that's needed for complete transparency (according to a Meridian Audio research paper).

I know nothing about the mastering/manufacturing costs of dual layer SACD/CDs vs. (region free) Blu-rays, is Blu-ray mastering/manufacturing a lot more expensive than SACD?

Yes, it is.
Which is hilarious to say the least.
Considering the hefty storage space of a BD~A disc compared to hybrid SACD, not surprised. A real shame that almost ALL single album BD~As

contain a sh*tload of unused storage capacity. I was really hoping when Universal announced their BD~A launch they'd release oodles of box sets in 96/24 resolution [stereo] on a single BD~A but that never transpired. IMO, it might've piqued an interest in BD~A but they, like all other major music labels, continue to release box sets on individual RBCDs in 44.1/16!

So much for forward thinking!

Time to play the guessing game of how many hours of 7.1 audio can fit on a bluray at 24/96 LCPM!
...
The answer is 3 hours on a single layer disc when you're wasting as much space as possible.
