You know that you can feed floating-points into mpa and get the same out and
there is also an extension for mc, so in theory you can get nearly the same
dynamics with mpa as with ac3, but usually tracks are not mixed this way and
as nearly no receiver handles mpa, it gets decoded to PCM anyway, so
practically you are right.
