You seem to be trying to have it both ways. If as you say digital has no
loss, then there is no need for a error-correction headroom meter.
What that error correction is dealing with is loss of data.
Yes, it's small, and a ten pass test won't even really make ATRAC break
out a sweat, let alone the so called lossless formats. But in digital we
make many more passes than that without even noticing them.
I got my info from folks who design the subroutines and hardware that's
inside our computers.
It's good enough not to be a problem, but there are errors. As in the
exact same bits don't always come back out of lossless digital processes
or transfers.
