Why just highbit digital signals, Cal?

Isn't it true that increasing the bitrate doesn't necessarily increase
precision, particularly if the increased bitrate comes from increased
sample rate and the signal being digitized is band-limted?

If the data were synchronous that would be so, but by definition
analog is async. Bicycle spokes and popsicle sticks and all that.

|| SACD and DVD-A have never impressed me as much as a few occasions
of
listening to either first rate vinyl or 1/2" 30 ips tape on a well
set
up Ampex.

So Cal, how old are you anyway? Offhand I would say that only an
octogenarian would fail to hear the way that vinyl trashes the audio
off a good high speed analog tape.

Younger than you, Arny.

Good analog tape is the gold standard, is it, Arny? Well, yes. But
really good vinyl comes moderately close. Maybe we should be arguing
for analog optical-sprocketless film on Ampex transports with
photocells instead of mag heads. But like turbine cars and Marilyn
singing anything Lennon-McCartney wrote, it wasn't to be and can't now.
