indeed. there are people who are coming to believe that
this "error" is responsible for a significant part of the audible
difference between digital and analog playback when the levels in
the source material are high.
It could be. OTOH, most DACs today would upsample and filter before
the real conversion takes place, and could allow for this. But maybe
they don't, and just clip at that point.
I would consider that a hardware bug - but you never know... If this
actually does happen, it would certainly cause a great deal of damage
with the kind of compression applied to most things these days.
