I do appreciate polemic, as long as it sticks with the truth...
In the 80s we had lousy vinyl, and nobody was saying anything about AAC-compressed, besides raising the question if maybe even AAC compressed files might be able to carry the signal.
The talk was about UHJ stereo compatible digital distribution, which in no way
implies lossy compression. Apple, to stick with that topic, doesn't create a
file format like ALAC and CAF for it not to be used, but they are not going to
use them, unless there's a meaningful purpose to do so. For plain stereo
delivery of random popular music, anything beyond 320kpbs AAC is pretty much
wasted bandwidth and storage.
Maybe not, because you add definitively two compressive steps.
Did you test this? If so, your case looks better, otherwise I am
listening to some very "tough" opinions. (You wanted to "kill the
engineers", which was way too polemic anyway.)
You also seem to think that 16 bits are enough FAPP, but orchestra
recordings have often more than 96dB dynamic range. I know that you can
hear under the noise floor. But then, you probably will hear also some
noise?
Let's now stay in this thread with 3D cinema sound, please. (And here
there are some real developments, for which I gave some links. I am not
talking just about < opinions > here.)
Best,

P.S.: Dolby Digital etc. offer a dynamic range which is greater than 16
bits.
Therefore, it is not "just" about classical music. (But then, a format
has to cover normal or usual cases, and in my opinion most people
actually do hear < some > classical music, i.e. < sometimes >.)
